Concepts

React Table is a "headless" UI library

React Table is a headless utility, which means out of the box, it doesn't render or supply any actual UI elements. You are in charge of utilizing the state and callbacks of the hooks provided by this library to render your own table markup. Read this article to understand why React Table is built this way.. If you don't want to, then here's a quick rundown anyway:

Separation of Concerns - Not that superficial kind you read about all the time. The real kind. React Table as a library honestly has no business being in charge of your UI. The look, feel, and overall experience of your table is what makes your app or product great. The less React Table gets in the way of that, the better!
Maintenance - By removing the massive (and seemingly endless) API surface area required to support every UI use-case, React Table can remain small, easy-to-use and simple to update/maintain.
Extensibility - UI presents countless edge cases for a library simply because it's a creative medium, and one where every developer does things differently. By not dictating UI concerns, React Table empowers the developer to design and extend the UI based on their unique use-case.

The React Table API

At the heart of every React Table is a table instance object. This object contains everything needed to build a table and interact with it's state. This includes, but is not limited to:

Columns
Materialized Data
Sorting
Filtering
Grouping
Pagination
Expanded State
Any functionality provided by custom plugin hooks, too!

Using Hooks for configuration, state and lifecycle

React Table uses React Hooks both internally and externally for 100% of its configuration and lifecycle management. Naturally, this is what allows React Table to be headless and lightweight while still having a concise and simple API.

React Table is essentially a compatible collection of custom React hooks:

The primary React Table hook
- useTable
Plugin Hooks
- Core Plugin Hooks
- Layout Plugin Hooks
  - useFlexLayout
  - useAbsoluteLayout (coming soon!)
Custom Plugin Hooks
- Get your custom plugin hook listed here!

Hook Usage

useTable is the primary hook used to build a React Table. It serves as the starting point for every option and every plugin hook that React Table supports. The options passed into useTable are supplied to every plugin hook after it in the order they are supplied, eventually resulting a final instance object that you can use to build your table UI and interact with the table's state.

const instance = useTable(
  {
    data: [...],
    columns: [...],
  },
  useGroupBy,
  useFilters,
  useSortBy,
  useExpanded,
  usePagination
)

The stages of a React Table

useTable is called. A table instance is created.
The instance.state is resolved from either a custom user state or an automatically generated one.
A collection of plugin points is created at instance.hooks.
Each plugin is given the opportunity to add hooks to instance.hook.
As the useTable logic proceeds to run, each plugin hook type is used at a specific point in time with each individual hook function being executed the order it was registered.
The final instance object is returned from useTable, which the developer then uses to construct their table.

This multi-stage process is the secret sauce that allows React Table plugin hooks to work together and compose nicely, while not stepping on each others toes.

To dive deeper into plugins, see Plugins and the Plugin Guide

Plugin Hook Order & Consistency

The order and usage of plugin hooks must follow The Laws of Hooks, just like any other custom hook. They must always be unconditionally called in the same order.

NOTE: In the event that you want to programmatically enable or disable plugin hooks, most of them provide options to disable their functionality, eg. options.disableSorting

Option Memoization

React Table relies on memoization to determine when state and side effects should update or be calculated. This means that every option you pass to useTable should be memoized either via React.useMemo (for objects) or React.useCallback (for functions).

API

`useTable`

Required

useTable is the root hook for React Table. To use it, pass it with an options object with at least a columns and rows value, followed by any React Table compatible hooks you want to use.

Table Options

The following options are supported via the main options object passed to useTable(options)

columns: Array<Column>
- Required
- Must be memoized
- The core columns configuration object for the entire table.
- Supports nested columns arrays via the column's columns key, eg. [{ Header: 'My Group', columns: [...] }]
data: Array<any>
- Required
- Must be memoized
- The data array that you want to display on the table.
state: TableStateTuple[stateObject, stateUpdater]
- Optional
- Must be memoized table state tuple. See useTableState for more information.
- The state/updater pair for the table instance. You would want to override this if you plan on controlling or hoisting table state into your own code.
- Defaults to using an internal useTableState() instance if not defined.
- See Controlling and Hoisting Table State
defaultColumn: Object
- Optional
- Defaults to {}
- The default column object for every column passed to React Table.
- Column-specific properties will override the properties in this object, eg. { ...defaultColumn, ...userColumn }
- This is particularly useful for adding global column properties. For instance, when using the useFilters plugin hook, add a default Filter renderer for every column, eg.{ Filter: MyDefaultFilterComponent }
debug: Bool
- Optional
- A flag to turn on debug mode.
- Defaults to false

`column` Options

The following options are supported on any column object you can pass to columns.

accessor: String | Function
- Required
- This string/function is used to build the data model for your column.
- The data returned by an accessor should be primitive and sortable.
- If a string is passed, the column's value will be looked up on the original row via that key, eg. If your column's accessor is firstName then its value would be read from row['firstName']. You can also specify deeply nested values with accessors like info.hobbies or even address[0].street
- If a function is passed, the column's value will be looked up on the original row using this accessor function, eg. If your column's accessor is row => row.firstName, then its value would be determined by passing the row to this function and using the resulting value.
id: String
- Required if accessor is a function
- This is the unique ID for the column. It is used by reference in things like sorting, grouping, filtering etc.
- If a string accessor is used, it defaults as the column ID, but can be overridden if necessary.
columns: Array<Column>
- Optional
- A nested array of columns.
- If defined, the column will act as a header group. Columns can be recursively nested as much as needed.
show: Boolean | Function
- Optional
- Defaults to true
- If set to false, the column will be hidden.
- If set to a function, it will be called with the current table instance and can then return true or false.
- The data model for hidden columns is still calculated including sorting, filters, and grouping.
Header: String | Function | React.Component => JSX
- Optional
- Defaults to ({ id }) => id
- Receives the table instance and column model as props
- Must either be a string or return valid JSX
- If a function/component is passed, it will be used for formatting the header value, eg. You can use a Header function to dynamically format the header using any table or column state.
Cell: Function | React.Component => JSX
- Optional
- Defaults to ({ value }) => value
- Receives the table instance and cell model as props
- Must return valid JSX
- This function (or component) is primarily used for formatting the column value, eg. If your column accessor returns a date object, you can use a Cell function to format that date to a readable format.

Instance Properties

The following properties are available on the table instance returned from useTable

headerGroups: Array<HeaderGroup>
- An array of normalized header groups, each containing a flattened array of final column objects for that row.
- See Header Group Properties for more information
columns: Array<Column>
- A flat array of all final column objects computed from the original columns configuration option.
- See Column Properties for more information
headers[] Array<Column>
- A nested array of final column objects, similar in structure to the original columns configuration option.
- See Column Properties for more information
rows: Array<Row>
- An array of materialized row objects from the original data array and columns passed into the table options
- See Row Properties for more information
getTableProps: Function(?props)
- Required
- This function is used to resolve any props needed for your table wrapper.
- Custom props may be passed. NOTE: Custom props will override built-in table props, so be careful!
prepareRow: Function(Row)
- Required
- This function is responsible for lazily preparing a row for rendering. Any row that you intend to render in your table needs to be passed to this function before every render.
- Why? Since table data could potentially be very large, it can become very expensive to compute all of the necessary state for every row to be rendered regardless if it actually is rendered or not (for example if you are paginating or virtualizing the rows, you may only have a few rows visible at any given moment). This function allows only the rows you intend to display to be computed and prepped with the correct state.

`HeaderGroup` Properties

The following additional properties are available on every headerGroup object returned by the table instance.

headers: Array<Column>
- Required
- The columns in this header group.
getHeaderGroupProps: Function(?props)
- Required
- This function is used to resolve any props needed for this header group's row.
- You can use the getHeaderGroupProps hook to extend its functionality.
- Custom props may be passed. NOTE: Custom props will override built-in table props, so be careful!

Column Properties

The following properties are available on every Column object returned by the table instance.

id: String
- The resolved column ID from either the column's accessor or the column's hard-coded id property
visible: Boolean
- The resolved visible state for the column, derived from the column's show property
render: Function(type: String | Function | Component, ?props)
- This function is used to render content in context of a column.
- If type is a string, will render using the column[type] renderer. React Table ships with default Header renderers. Other renderers like Filter are available via hooks like useFilters.
- If a function or component is passed instead of a string, it will be be passed the table instance and column model as props and is expected to return any valid JSX.
getHeaderProps: Function(?props)
- Required
- This function is used to resolve any props needed for this column's header cell.
- You can use the getHeaderProps hook to extend its functionality.
- Custom props may be passed. NOTE: Custom props will override built-in table props, so be careful!

Row Properties

The following additional properties are available on every row object returned by the table instance.

cells: Array<Cell>
- An array of Cell objects containing properties and functions specific to the row and column it belongs to.
- See Cell Properties for more information
values: Object<columnID: any>
- A map of this row's resolved values by columnID, eg. { firstName: 'Tanner', lastName: 'Linsley' }
getRowProps: Function(?props)
- Required
- This function is used to resolve any props needed for this row.
- You can use the getRowProps hook to extend its functionality.
- Custom props may be passed. NOTE: Custom props will override built-in table props, so be careful!

Cell Properties

The following additional properties are available on every Cell object returned in an array of cells on every row object.

column: Column
- The corresponding column object for this cell
row: Row
- The corresponding row object for this cell
value: any
- The resolved value for this cell.
- By default, this value is displayed on the table via the default Cell renderer. To override the way a cell displays
getCellProps: Function(?props)
- Required
- This function is used to resolve any props needed for this cell.
- You can use the getCellProps hook to extend its functionality.
- Custom props may be passed. NOTE: Custom props will override built-in table props, so be careful!
render: Function(type: String | Function | Component, ?props)
- This function is used to render content in context of a cell.
- If type is a string, will render using the column[type] renderer. React Table ships with a default Cell renderer. Other renderers like Aggregated are available via hooks like useFilters.
- If a function or component is passed instead of a string, it will be be passed the table instance and cell model as props and is expected to return any valid JSX.

Example

function App() {
  const columns = React.useMemo(
    () => [
      {
        Header: 'Name',
        columns: [
          {
            Header: 'First Name',
            accessor: 'firstName',
          },
          {
            Header: 'Last Name',
            accessor: 'lastName',
          },
        ],
      },
    ],
    []
  )

  const data = [
    {
      firstName: 'Tanner',
      lastName: 'Linsley',
    },
    {
      firstName: 'Shawn',
      lastName: 'Wang',
    },
    {
      firstName: 'Kent C.',
      lastName: 'Dodds',
    },
    {
      firstName: 'Ryan',
      lastName: 'Florence',
    },
  ]

  return <MyTable columns={columns} data={data} />
}

function MyTable({ columns, data }) {
  const { getTableProps, headerGroups, rows, prepareRow } = useTable({
    columns,
    data,
  })

  return (
    <table {...getTableProps()}>
      <thead>
        {headerGroups.map(headerGroup => (
          <tr {...headerGroup.getHeaderGroupProps()}>
            {headerGroup.headers.map(column => (
              <th {...column.getHeaderProps()}>{column.render('Header')}</th>
            ))}
          </tr>
        ))}
      </thead>
      <tbody>
        {rows.map(
          (row, i) =>
            prepareRow(row) || (
              <tr {...row.getRowProps()}>
                {row.cells.map(cell => {
                  return <td {...cell.getCellProps()}>{cell.render('Cell')}</td>
                })}
              </tr>
            )
        )}
      </tbody>
    </table>
  )
}

`useSortBy`

Plugin Hook
Optional

useSortBy is the hook that implements row sorting. It also support multi-sort (keyboard required).

Multi-sort is enabled by default
To sort the table via UI, attach the props generated from each column's getSortByToggleProps(), then click any of those elements.
To multi-sort the table via UI, hold shift while clicking on any of those same elements that have the props from getSortByToggleProps() attached.
To programmatically sort (or multi-sort) any column, use the toggleSortBy method located on the instance or each individual column.

Table Options

The following options are supported via the main options object passed to useTable(options)

state[0].sortBy: Array<Object<id: columnID, desc: Bool>>
- Must be memoized
- An array of sorting objects. If there is more than one object in the array, multi-sorting will be enabled. Each sorting object should contain an id key with the corresponding column ID to sort by. An optional desc key may be set to true or false to indicated ascending or descending sorting for that column. This information is stored in state since the table is allowed to manipulate the filter through user interaction.
manualSorting: Bool
- Enables sorting detection functionality, but does not automatically perform row sorting. Turn this on if you wish to implement your own sorting outside of the table (eg. server-side or manual row grouping/nesting)
disableSorting: Bool
- Disables sorting for every column in the entire table.
disableMultiSort: Bool
- Disables multi-sorting for the entire table.
disableSortRemove: Bool
- If true, the un-sorted state will not be available to columns once they have been sorted.
disableMultiRemove: Bool
- If true, the un-sorted state will not be available to multi-sorted columns.
orderByFn: Function
- Must be memoizd
- Defaults to the built-in default orderBy function
- This function is responsible for composing multiple sorting functions together for multi-sorting, and also handles both the directional sorting and stable-sorting tie breaking. Rarely would you want to override this function unless you have a very advanced use-case that requires it.
sortTypes: Object<sortKey: sortType>
- Must be memoized
- Allows overriding or adding additional sort types for columns to use. If a column's sort type isn't found on this object, it will default to using the built-in sort types.
- For mor information on sort types, see Sorting

Column Options

The following options are supported on any Column object passed to the columns options in useTable()

disableSorting: Bool
- Optional
- Defualts to false
- If set to true, the sorting for this column will be disabled
sortDescFirst: Bool
- Optional
- Defaults to false
- If set to true, the first sort direction for this column will be descending instead of ascending
sortInverted: Bool
sortType: String | Function
- If a function is passed, it must be memoized
- Defaults to alphanumeric
- The resolved function from the this string/function will be used to sort the this column's data.
  - If a string is passed, the function with that name located on either the custom sortTypes option or the built-in sorting types object will be used. If
  - If a function is passed, it will be used.
- For mor information on sort types, see Sorting

Instance Properties

The following values are provided to the table instance:

rows: Array<Row>
- An array of sorted rows.
preSortedRows: Array<Row>
- The array of rows that were originally sorted.
toggleSortBy: Function(ColumnID: String, descending: Bool, isMulti: Bool) => void
- This function can be used to programmatically toggle the sorting for any specific column

Column Properties

The following properties are available on every Column object returned by the table instance.

canSort: Bool
- Denotes whether a column is sortable or not depending on if it has a valid accessor/data model or is manually disabled via an option.
toggleSortBy: Function(descending, multi) => void
- This function can be used to programmatically toggle the sorting for this column.
- This function is similar to the instance-level toggleSortBy, however, passing a columnID is not required since it is located on a Column object already.
getSortByToggleProps: Function(props) => props
- Required
- This function is used to resolve any props needed for this column's UI that is responsible for toggling the sort direction when the user clicks it.
- You can use the getSortByToggleProps hook to extend its functionality.
- Custom props may be passed. NOTE: Custom props may override built-in sortBy props, so be careful!
sorted: Boolean
- Denotes whether this column is currently being sorted
sortedIndex: Int
- If the column is currently sorted, this integer will be the index in the sortBy array from state that corresponds to this column.
- If this column is not sorted, the index will always be -1
sortedDesc: Bool
- If the column is currently sorted, this denotes whether the column's sort direction is descending or not.
- If true, the column is sorted descending
- If false, the column is sorted ascending
- If undefined, the column is not currently being sorted.

Example

function Table({ columns, data }) {
  // Set some default sorting state
  const state = useTableState({ sortBy: [{ id: 'firstName', desc: true }] })

  const { getTableProps, headerGroups, rows, prepareRow } = useTable(
    {
      columns,
      data,
    },
    useSortBy // Use the sortBy hook
  )

  return (
    <table {...getTableProps()}>
      <thead>
        {headerGroups.map(headerGroup => (
          <tr {...headerGroup.getHeaderGroupProps()}>
            {headerGroup.headers.map(column => (
              // Add the sorting props to control sorting. For this example
              // we can add them into the header props
              <th {...column.getHeaderProps(column.getSortByToggleProps())}>
                {column.render('Header')}
                <span>
                  {/* Add a sort direction indicator */}
                  <span>
                    {column.sorted ? (column.sortedDesc ? ' 🔽' : ' 🔼') : ''}
                  </span>
                  {/* Add a sort index indicator */}
                  <span>({column.sorted ? column.sortedIndex + 1 : ''})</span>
                </span>
              </th>
            ))}
          </tr>
        ))}
      </thead>
      <tbody>
        {rows.map(
          (row, i) =>
            prepareRow(row) || (
              <tr {...row.getRowProps()}>
                {row.cells.map(cell => {
                  return <td {...cell.getCellProps()}>{cell.render('Cell')}</td>
                })}
              </tr>
            )
        )}
      </tbody>
    </table>
  )
}

`useFilters`

Plugin Hook
Optional

useFilters is the hook that implements row filtering.

Table Options

The following options are supported via the main options object passed to useTable(options)

state[0].filters: Object<columnID: filterValue>
- Must be memoized
- An object of columnID's and their corresponding filter values. This information is stored in state since the table is allowed to manipulate the filter through user interaction.
defaultFilter: String | Function
- If a function is passed, it must be memoized
- Defaults to text
- The function (or resolved function from the string) will be used as the default/fallback filter method for every column that has filtering enabled.
  - If a string is passed, the function with that name located on the filterTypes option object will be used.
  - If a function is passed, it will be used.
- For mor information on filter types, see Filtering
manualFilters: Bool
- Enables filter detection functionality, but does not automatically perform row filtering.
- Turn this on if you wish to implement your own row filter outside of the table (eg. server-side or manual row grouping/nesting)
disableFilters: Bool
- Disables filtering for every column in the entire table.
filterTypes: Object<filterKey: filterType>
- Must be memoized
- Allows overriding or adding additional filter types for columns to use. If a column's filter type isn't found on this object, it will default to using the built-in filter types.
- For mor information on filter types, see Filtering

Column Options

The following options are supported on any Column object passed to the columns options in useTable()

Filter: Function | React.Component => JSX
- Required
- Receives the table instance and column model as props
- Must return valid JSX
- This function (or component) is used to render this column's filter UI, eg.
disableFilters: Bool
- Optional
- If set to true, will disable filtering for this column
filter: String | Function
- Optional
- Defaults to text
- The resolved function from the this string/function will be used to filter the this column's data.

Instance Properties

The following values are provided to the table instance:

rows: Array<Row>
- An array of filtered rows.
preFilteredRows: Array<Row>
- The array of rows used right before filtering.
- Among many other use-cases, these rows are directly useful for building option lists in filters, since the resulting filtered rows do not contain every possible option.
setFilter: Function(columnID, filterValue) => void
- An instance-level function used to update the filter value for a specific column.
setAllFilters: Function(filtersObject) => void
- An instance-level function used to update the values for all filters on the table, all at once.

Column Properties

The following properties are available on every Column object returned by the table instance.

canFilter: Bool
- Denotes whether a column is filterable or not depending on if it has a valid accessor/data model or is manually disabled via an option.
setFilter: Function(filterValue) => void
- An column-level function used to update the filter value for this column
filterValue: any
- The current filter value for this column, resolved from the table state's filters object
preFilteredRows: Array<row>
- The array of rows that were originally passed to this columns filter before they were filtered.
- This array of rows can be useful if building faceted filter options.

Example

// A great library for fuzzy filtering/sorting items
import matchSorter from 'match-sorter'

const state = useTableState({ filters: { firstName: 'tanner' } })

const filterTypes = React.useMemo(() => ({
  // Add a new fuzzyText filter type.
  fuzzyText: (rows, id, filterValue) => {
    return matchSorter(rows, filterValue, { keys: [row => row[id] })
  },
  // Or, override the default text filter to use
  // "startWith"
  text: (rows, id, filterValue) => {
    return rows.filter(row => {
      const rowValue = row.values[id]
      return rowValue !== undefined
        ? String(rowValue)
            .toLowerCase()
            .startsWith(String(filterValue).toLowerCase())
        : true
    })
  }
}), [matchSorter])

// Override the default column filter to be our new `fuzzyText` filter type
const defaultColumn = React.useMemo(() => ({
  filter: 'fuzzyText'
}))

const { rows } = useTable(
  {
    // state[0].groupBy === ['firstName']
    state,
    manualFilters: false,
    disableFilters: false,
    // Pass our custom filter types
    filterTypes,
    defaultColumn
  },
  useFilters
)

`useGroupBy`

Plugin Hook
Optional

useGroupBy is the hook that implements row grouping and aggregation.

Each column's getGroupByToggleProps() function can be used to generate the props needed to make a clickable UI element that will toggle the grouping on or off for a specific column.
Instance and column-level toggleGroupBy functions are also made available for programmatic grouping.

Table Options

The following options are supported via the main options object passed to useTable(options)

state[0].groupBy: Array<String>
- Must be memoized
- An array of groupBy ID strings, controlling which columns are used to calculate row grouping and aggregation. This information is stored in state since the table is allowed to manipulate the groupBy through user interaction.
manualGroupBy: Bool
- Enables groupBy detection and functionality, but does not automatically perform row grouping.
- Turn this on if you wish to implement your own row grouping outside of the table (eg. server-side or manual row grouping/nesting)
disableGrouping: Bool
- Disables groupBy for the entire table.
aggregations: Object<aggregationKey: aggregationFn>
- Must be memoized
- Allows overriding or adding additional aggregation functions for use when grouping/aggregating row values. If an aggregation key isn't found on this object, it will default to using the built-in aggregation functions
groupByFn: Function
- Must be memoized
- Defaults to defaultGroupByFn
- This function is responsible for grouping rows based on the state.groupBy keys provided. It's very rare you would need to customize this function.

Column Options

The following options are supported on any Column object passed to the columns options in useTable()

Aggregated: Function | React.Component => JSX
- Optional
- Defaults to this column's Cell formatter
- Receives the table instance and cell model as props
- Must return valid JSX
- This function (or component) formats this column's value when it is being grouped and aggregated, eg. If this column was showing the number of visits for a user to a website and it was currently being grouped to show an average of the values, the Aggregated function for this column could format that value to 1,000 Avg. Visits
disableGrouping: Boolean
- Defaults to true
- If true, this column is able to be grouped.

Instance Properties

The following values are provided to the table instance:

rows: Array<Row>
- An array of grouped and aggregated rows.
preGroupedRows: Array<Row>
- The array of rows originally used to create the grouped rows.
toggleGroupBy: Function(columnID: String, ?set: Bool) => void
- This function can be used to programmatically set or toggle the groupBy state for a specific column.

Column Properties

The following properties are available on every Column object returned by the table instance.

canGroupBy: Boolean
- If true, this column is able to be grouped.
- This is resolved from the column having a valid accessor / data model, and not being manually disabled via other useGroupBy related options
grouped: Boolean
- If true, this column is currently being grouped
groupedIndex: Int
- If this column is currently being grouped, this integer is the index of this column's ID in the table state's groupBy array.
toggleGroupBy: Function(?set: Bool) => void
- This function can be used to programmatically set or toggle the groupBy state fo this column.
getGroupByToggleProps: Function(props) => props
- Required
- This function is used to resolve any props needed for this column's UI that is responsible for toggling grouping when the user clicks it.
- You can use the getGroupByToggleProps hook to extend its functionality.
- Custom props may be passed. NOTE: Custom props may override built-in sortBy props, so be careful!

Row Properties

The following properties are available on every Row object returned by the table instance.

groupByID: String
- The column ID for which this row is being grouped.
- Will be undefined if the row is an original row from data and not a materialized one from the grouping.
groupByVal: any
- If the row is a materialized group row, this will be the grouping value that was used to create it.
values: Object
- Similar to a regular row, a materialized grouping row also has a values object
- This object contains the aggregated values for this row's sub rows
subRows: Array<Row>
- If the row is a materialized group row, this property is the array of materialized subRows that were grouped inside of this row.
depth: Int
- If the row is a materialized group row, this is the grouping depth at which this row was created.
path: Array<String|Int>
- Similar to normal Row objects, materialized grouping rows also have a path array. The keys inside it though are not integers like nested normal rows though. Since they are not rows that can be traced back to an original data row, they are given a unique path based on their groupByVal
- If a row is a grouping row, it will have a path like ['Single'] or ['Complicated', 'Anderson'], where Single, Complicated, and Anderson would all be derived from their row's groupByVal.

Cell Properties

The following additional properties are available on every Cell object returned in an array of cells on every row object.

grouped: Bool
- If true, this cell is a grouped cell, meaning it contains a grouping value and should usually display and expander.
repeatedValue: Bool
- If true, this cell is a repeated value cell, meaning it contains a value that is already being displayed elsewhere (usually by a parent row's cell).
- Most of the time, this cell is not required to be displayed and can safely be hidden during rendering
aggregated: Bool
- If true, this cell's value has been aggregated and should probably be rendered with the Aggregated cell renderer.

`useExpanded`

Plugin Hook
Optional

useExpanded is the hook that implements row expanding. It is most often used with useGroupBy to expand grouped rows, but is not limited to that use-case. It supports expanding rows both via internal table state and also via a hard-coded key on the raw row model.

Table Options

The following options are supported via the main options object passed to useTable(options)

state[0].expanded: Object<[pathIndex]: Boolean | ExpandedStateObject>
- Must be memoized
- An nested object of expanded paths.
- A pathIndex can be set as the key and its value set to true to expand that row's subRows into view. For example, if { '3': true } was passed as the expanded state, the 4th row in the original data array would be expanded.
- For nested expansion, you may use another object instead of a Boolean to expand sub rows. For example, if { '3': { '5' : true }} was passed as the expanded state, then the 6th subRow of the 4th row and the 4th row of the original data array would be expanded.
- This information is stored in state since the table is allowed to manipulate the filter through user interaction.
subRowsKey: String
- Required
- Defaults to subRows
- React Table will use this key when materializing the final row object. It also uses this key to infer sub-rows from the raw data.
- See Grouping and Aggregation for more information
paginateSubRows: Bool
- Defaults to true
- If set to false, expanded rows will not be paginated. Thus, any expanded subrows would potentially increase the size of any given page by the amount of total expanded subrows on the page.
manualExpandedKey: String
- Defaults to expanded
- This string is used as the key to detect manual expanded state on any given row. For example, if a raw data row like { name: 'Tanner Linsley', friends: [...], expanded: true} was detected, it would be forcibly expanded, regardless of state.

Instance Variables

The following values are provided to the table instance:

rows: Array<Row>
- An array of sorted rows.

Example

const state = useTableState({ expanded: { '3': true, '5': { '2': true } } })

const { rows } = useTable(
  {
    // state[0].sortBy === { '3': true, '5': { '2': true } }
    state,
  },
  useExpanded
)

`usePagination`

Plugin Hook
Optional

usePagination is the hook that implements row pagination. It can be used for both client-side pagination or server-side pagination. For more information on pagination, see Pagination

NOTE Some server-side pagination implementations do not use page index and instead use token based pagination! If that's the case, please use the useTokenPagination plugin instead.

Table Options

The following options are supported via the main options object passed to useTable(options)

state[0].pageSize: Int
- Required
- Defaults to 10
- Determines the amount of rows on any given page
state[0].pageIndex: Int
- Required
- Defaults to 0
- The index of the page that should be displayed via the page instance value
pageCount: Int
- Required if manualPagination is set to true
- If manualPagination is true, then this value used to determine the amount of pages available. This amount is then used to materialize the pageOptions and also compute the canNextPage values on the table instance.
manualPagination: Bool
- Enables pagination functionality, but does not automatically perform row pagination.
- Turn this on if you wish to implement your own pagination outside of the table (eg. server-side pagination or any other manual pagination technique)
disablePageResetOnDataChange
- Defaults to false
- Normally, any changes detected to rows, state.filters, state.groupBy, or state.sortBy will trigger the pageIndex to be reset to 0
- If set to true, the pageIndex will not be automatically set to 0 when these dependencies change.

Instance Variables

The following values are provided to the table instance:

pages: Array<page>
- An array of every generated page, each containing its respective rows.
page: Array<row>
- An array of rows for the current page, determined by the current pageIndex value.
pageCount: Int
- If manualPagination is set to false, this is the total amount of pages available in the table based on the current pageSize value
- if manualPagination is set to true, this is merely the same pageCount option that was passed in the table options.
pageOptions: Array<Int>
- An array of zero-based index integers corresponding to available pages in the table.
- This can be useful for generating things like select interfaces for the user to select a page from a list, instead of manually paginating to the desired page.
canPreviousPage: Bool
- If there are pages and the current pageIndex is greater than 0, this will be true
canNextPage:
- If there are pages and the current pageIndex is less than pageCount, this will be true
gotoPage: Function(pageIndex)
- This function, when called with a valid pageIndex, will set pageIndex to that value.
- If the passed index is outside of the valid pageIndex range, then this function will do nothing.
previousPage: Function
- This function decreases state.pageIndex by one.
- If there are no pages or canPreviousPage is false, this function will do nothing.
nextPage: Function
- This function increases state.pageIndex by one.
- If there are no pages or canNextPage is false, this function will do nothing.
setPageSize: Function(pageSize)
- This function sets state.pageSize to the new value.
- As a result of a pageSize change, a new state.pageIndex is also calculated. It is calculated via Math.floor(currentTopRowIndex / newPageSize)
pageIndex: Int
- This is the resolved state.pageIndex value.
pageSize: Int
- This is the resolved state.pageSize value.

Example

const state = useTableState({ pageSize: 20, pageIndex: 1 })

const { rows } = useTable(
  {
    // state[0] === { pageSize: 20, pageIndex: 1 }
    state,
  },
  usePagination
)

`useTokenPagination`

Plugin Hook
Optional

useTokenPagination is the hook that aids in implementing row pagination using tokens. It is useful for server-side pagination implementations that use tokens instead of page index. For more information on pagination, see Pagination

Documentation Coming Soon...

`useTableState`

Optional

useTableState is a hook that allows you to hoist the table state out of the table into your own code. You should use this hook if you need to:

Know about the internal table state
React to changes to the internal table state
Manually control or override the internal table state

Some common use cases for this hook are:

Reacting to pageIndex and pageSize changes for server-side pagination to fetch new data
Disallowing specific states via a custom state reducer
Enabling parent/unrelated components to manipulate the table state

Table Options

The following options are supported via the main options object passed to useTable(options)

initialState: Object
- Optional
- The initial state object for the table.
- This object is merged over the defaultState object (eg. {...defaultState, ...initialState}) that React Table and its hooks use to register default state to produce the final initial state object passed to the resolved useState hook.
overrides: Object
- Optional
- Must be memoized
- This object is merged over the current table state (eg. {...state, ...overrides}) to produce the final state object that is then passed to the useTable options
options: Object
- reducer: Function(oldState, newState) => finalState
  - Optional
  - Inspired by Kent C. Dodd's State Reducer Pattern
  - With every setState call to a table state (even internally), this reducer is called and is allowed to modify the final state object for updating.
  - It is passed the oldState, the newState, and an action type.
- useState
  - Optional
  - Defaults to React.useState
  - This function, if defined will be used as the state hook internally instead of the default React.useState. This can be useful for implementing custom state storage hooks like useLocalStorage, etc.

Instance Variables

tableStateTuple: [tableState, setTableState]
- Similar in structure to the result of React.useState
- Memoized. This tuple array will not change between renders unless state or useTableState options change.
- tableState: Object
  - This is the final state object of the table, which is the product of the initialState, overrides and the reducer options (if applicable)
- setTableState: Function(updater, type) => void
  - This function is used both internally by React Table, and optionally by you (the developer) to update the table state programmatically.
  - updater: Function
    - This function signature is almost (see next point) identical to the functional API exposed by React.setState. It is passed the previous state and is expected to return a new version of the state.
    - NOTE: updater must be a function. Passing a replacement object is not supported as it is with React.useState
  - type: String
    - The action type corresponding to what action being taken against the state.

Example

export default function MyTable({ manualPageIndex }) {
  // This is the initial state for our table
  const initialState = { pageSize: 10, pageIndex: 0 }

  // Here, we can override the pageIndex
  // regardless of the internal table state
  const overrides = React.useMemo(() => ({
    pageIndex: manualPageIndex,
  }))

  const state = useTableState(initialState, overrides)

  // You can use effects to observe changes to the state
  React.useEffect(
    () => {
      console.log('Page Size Changed!', initialState.pageSize)
    },
    [initialState.pageSize]
  )

  const { rows } = useTable({
    state,
  })
}

Sorting

Client-Side Sorting

Example

Client-side sorting can be accomplished by using the useSortBy plugin hook. Start by importing the hook from react-table:

-import { useTable } from 'react-table'
+import { useTable, useSortBy } from 'react-table'

Next, add the useSortBy hook to your useTable hook and add the necessary UI pieces we need to make sorting work:

function MyTable() {
  const { getTableProps, headerGroups, rows, prepareRow } = useTable(
    {
      data,
      columns,
    },
-   useSortBy
+   useSortBy
  )

  return (
    <table {...getTableProps()}>
      <thead>
        {headerGroups.map(headerGroup => (
          <tr {...headerGroup.getHeaderGroupProps()}>
            {headerGroup.headers.map(column => (
-             <th {...column.getHeaderProps()}>
+             <th {...column.getHeaderProps(column.getSortByToggleProps())}>
                {column.render('Header')}
+               <span>
+                 {column.sorted ? (column.sortedDesc ? ' 🔽' : ' 🔼') : ''}
+               </span>
              </th>
            ))}
          </tr>
        ))}
      </thead>
      <tbody>
        {rows.map(
          (row, i) =>
            prepareRow(row) || (
              <tr {...row.getRowProps()}>
                {row.cells.map(cell => {
                  return <td {...cell.getCellProps()}>{cell.render('Cell')}</td>
                })}
              </tr>
            )
        )}
      </tbody>
    </table>
  )
}

Server-Side Sorting

Server-side sorting can be accomplished by using the useSortBy plugin hook in controlled mode along with the useTableState hook. Start by importing these hooks from react-table:

-import { useTable } from 'react-table'
+import { useTable, useSortBy, useTableState } from 'react-table'

Next, add the useSortBy and useTableState hooks to your useTable hook, configure the table state, then add the necessary UI pieces we need to make sorting work:

function MyTable(data, columns, fetchData) {

+ const state = useTableState()
+ const [{ sortBy }] = state

+ React.useEffect(() => {
+   // When sorting changes, trigger your parent component
+   // or hook to fetch new data with the table state
+   fetchData(state[0])
+ }, [sortBy])

  const { getTableProps, headerGroups, rows, prepareRow } = useTable(
    {
      data,
      columns,
+     state,
+     manualSorting: true
    },
-   useSortBy
+   useSortBy
  )

  return (
    <table {...getTableProps()}>
      <thead>
        {headerGroups.map(headerGroup => (
          <tr {...headerGroup.getHeaderGroupProps()}>
            {headerGroup.headers.map(column => (
-             <th {...column.getHeaderProps()}>
+             <th {...column.getHeaderProps(column.getSortByToggleProps())}>
                {column.render('Header')}
+               <span>
+                 {column.sorted ? (column.sortedDesc ? ' 🔽' : ' 🔼') : ''}
+               </span>
              </th>
            ))}
          </tr>
        ))}
      </thead>
      <tbody>
        {rows.map(
          (row, i) =>
            prepareRow(row) || (
              <tr {...row.getRowProps()}>
                {row.cells.map(cell => {
                  return <td {...cell.getCellProps()}>{cell.render('Cell')}</td>
                })}
              </tr>
            )
        )}
      </tbody>
    </table>
  )
}
