AngularJS Table directive

This directive draws a table of data with different features. It has no dependency other than angularjs. It has been tested on Google Chrome, Safari, Opera and Firefox and Internet Explorer 10 (8+ in developer mode)

To use this directive, just add the ngcTableDirective as dependency. The template is handled as an external HTML file and integrated during the build process in the ngc-template module. The template is registered in the angularjs template cache with the key ngc.table.tpl.html


  • Automatic column and row references like in popular spreadsheets
  • Any number of fixed left and right columns
  • Any number of fixed header and footer rows
  • No table redraw : Supports big data sets without impacting display speed
  • Scrolls on full rows and columns
  • Support scrolling on mobile devices with touch events
  • Data ranges with custom CSS class, format and styling functions and event callbacks
  • Append custom sanitized or trusted HTML elements in cells (v0.2.0)
  • Table elements CSS classes for easy theming
  • No dependency except AngularJS



The directive displays a grid of cells organized as the following principles :

| |      COLUMN LETTERS        |
| |      | HEADER ROWS |       |
|R|      |             |       |
|O| LEFT |   CENTER    | RIGHT |
|W| COLS |    COLS     | COLS  |
|#|      |             |       |
| |      | FOOTER ROWS |       |

When the data matrix vertical dimension than the total number of rows, the area between header and footer is scrollable. The behaviour is identical for the number of columns, the area between the left and right columns becomes scrollable.

ng-cells is also available through bower (bower install ng-cells)

Minimal example to display a table with one million cells (1000 x 1000 data matrix) with default settings and no styling :

<!DOCTYPE html>
<html ng-app="ngcTableDirectiveTest">
    <title>Test Template</title>
    <link href="../dist/ng-cells-0.1.1.css" rel="stylesheet" type="text/css">
    <script src="../lib/angular-1.2.6.js"></script>
    <script src="../dist/ng-cells-0.1.1.js"></script>
        angular.module('ngcTableDirectiveTest', ['ngcTableDirective'])
                .controller('TestCtrl', function($scope) {
                    $ = [];

                    for (var row = 0; row < 1000; row++) {
                        var rowContent = [];
                        for (var col = 0; col < 1000; col++) {
                            rowContent.push(row * col + col);



<div ng-controller="TestCtrl">
    <div ngc-table data="data"></div>

The data must be given as a two dimensional array (ie array[][]). If your data is a complex object, you can define a custom data function to extract the data value. For example, the following html snippet will use the below javascript function to get the value

<div ngc-table data="data" custom-data-value-fn="customDataFn"></div>
$scope.customDataFn = function(data, row, col) {
    return data[1000 - row - 1][1000 - col - 1];

The table settings like number of columns and rows in each table part can be specified with different attributes which names should be self-explanatory. Please see the reference below. For example:

        left-column-number="5" left-column-widths="'30px'"
        center-column-number="10" center-column-widths="['40px', '60px', '40px']"
        right-column-number="5" right-column-widths="['60px', '40px', '60px', '40px', '60px']"
        header-row-number="2" header-row-heights="['30px', '15px']"
        row-number='15' row-heights="['41px', '14px']"
        footer-row-number="3" footer-row-heights="'24px'">

Cell Ranges


Ranges let specify custom behaviour for data ranges. The range is defined by the area limits and holds custom CSS classes, format and styling functions and event callbacks. Ranges are specified in the data matrix range, thus they are not related to cells.

To add custom ranges, use the declarative ranges definitions such as this example :

 <ngc-table data="data">
     <ngc-range top="0" bottom="1000" left="0" right="5" format-fn="cellFormatRange1"></ngc-range>
     <ngc-range top="3" bottom="8" left="3" right="998" format-fn="cellFormatRange2"></ngc-range>
     <ngc-range top="10" bottom="12" left="6" right="15" format-fn="cellFormatRange3"></ngc-range>
     <ngc-range top="13" bottom="30" left="3" right="998" format-fn="cellFormatRange4"></ngc-range>
     <ngc-range top="990" bottom="998" left="3" right="998"></ngc-range>

Ranges can overlap but only one class, event function, format function etc is activated on a single cell. The order of precedence is the same as the order of the range declarations. The callback receives the cell and the cellData.

Here an example of mousemove event handling :

<ngc-range top="0" bottom="5" left="0" right="5" click-fn="clickFn"  ></ngc-range>
$scope.clickFn = function(event, cellData) {

CSS Classes

In addition to ranges custom classes, the table embeds CSS classes to identify each part of the table. For example, to set the pen color and the background color of all cells of the right header part, use the following CSS statement in your stylesheet. If you have other elements that clash you can add an additional ngc class to make it more specific.

.cell.right.header {
    background-color: #880000;
    color: whitesmoke;

Directive Reference


  • data The 2D data matrix. The matrix can be of any dimension. By default, the displayed data is the data raw value
  • custom-data-value-fn A custom function to extract the data value from the data source. The provided function should have the form function(data, row, col). Please remember that the initial data matrix IS required in order to define the data dimensions. function(event, scrollPosition) where event is the scroll event and scrollPosition is an object with top and left attributes. The top and left attributes are the row and column of the data value displayed in the top left corner of the middle center area. This function is called once when the table is firstly drawn to give the opportunity to store initial top left values.
  • show-column-names A flag to set the visibility of the column letters. By default true
  • show-row-numbers A flag to set the visibility of the row numbers. By default true
  • show-header A flag to set the visibility of the header part. By default true. If false, the value of header-row-number is ignored
  • show-footer A flag to set the visibility of the footer part. By default true. If false, the value of footer-row-number is ignored
  • left-column-number The number of fixed columns on the left part of the table. By default 1
  • left-column-widths The CSS width of the left fixed columns, expressed with unit (eg '40px'). No default. The value can be a single string value or an array of string values. If the value is a single string, the same width is applied to all columns. If the value is an array, each column gets the width in arrays order (if the array's length is smaller than the number columns, the last width is used for the remaining columns).
  • center-column-number The number of columns on the center part of the table. By default 10
  • center-column-widths The width of the center columns. See left-column-widths for value specification
  • right-column-number The number of fixed columns on the right part of the table. By default 1
  • right-column-widths The width of the right fixed columns. See left-column-widths for value specification
  • header-row-number The number of rows in the header section of the table
  • header-row-heights The height of the header rows. See left-column-widths for value specification (except that the array values obviously relate to rows and not columns)
  • row-number The number of rows in the middle section of the table
  • row-heights The height of the middle rows. See header-row-heights for value specification
  • footer-row-number The number of rows in the footer section of the table
  • footer-row-heights The height of the footer rows. See header-row-heights for value specification
  • scroll-top-position The vertical scroll position. This attribute can be set to scroll programmatically. The diagonalScroll.html test file shows how to bind horizontal and vertical scrollbars
  • scroll-left-position The horizontal scroll position. See scroll-top-position


  • top The top row (inclusive) limit of this range
  • bottom The bottom (non-inclusive) row limit of this range
  • left The left (inclusive) column limit of this range
  • right The right (non-inclusive) column limit of this range
  • format-fn A custom format function. This can be used to customize the output format of the data value. The function must be of the form function(value, row, col) where value is the value of the source data at the position [row][col]
  • clazz Class(es) to add to the cells enclosed by the range
  • custom-html-fn A custom function to insert custom HTML in the cells. The returned HTML is sanitized by AngularJS before being injected. Please use the custom-trusted-html-fn function if you want to bypass the sanitizer parser. The function must be of the form function(value, row, col, formattedValue) where value is the value of the source data at the position [row][col] and formattedValue contains the value after being formatted. The function must return a string containing the HTML
  • custom-trusted-html-fn A custom function to insert custom HTML in the cells. The returned HTML is not processed by the AngularJS sanitizer. For security reason, it is better to use the custom-html-fn. The function has the same form as custom-html-fn
  • style-fn A custom style format function to be applied to the cells. Use it to apply sophisticated styling to the table. The function must be of the form function(value, row, col) where value is the value of the source data at the position [row][col]
  • style A custom style format to be directly applied to the cells. If provided, it is added to the style from the style-fn above.
  • <event>-fn Custom event callbacks. The event can be any of click, dblclick, mousedown, mouseenter, mouseleave mousemove, mouseover, mouseup event types. The callback must be of the form function(event, cellData) where event is the initial Javascript event and the cellData an object with the following attributes :
    • row The row of the data value in original data space (not table space)
    • col The column of the data value in original data space (not table space)
    • data The original data value located at row and column
    • value The value of the cell as displayed
    • clazz The classes of the cell
    • style The style declaration of the cell
    • eventCallbacks An object with all registered callbacks identified the event type
    • enclosingRanges An array of all ranges that enclose the current cell
  • custom-cell-template Render a custom Angular template in the cell instead of using custom-html-fn.
    Accepts types:
    • string: URL of an Angular template. E.g. custom-cell-template="'template.html'"
    • Function: function that returns the URL of an Angular template. E.g. custom-cell-template="getTemplate"
      Function signature is function(rawData, row, col, formattedValue, scope) where rawData is an object that describes the table cell. points to the actual cell value.

**Note:** The cell value is stored in `scopeExtension.rawCellData` and can be accessed in the Angular template as follow: `{{}}`.
See test case [./test/custom-cell-template.html](./test/custom-cell-template.html) for a full example.

CSS Reference

Here's a list of the classes which can be used to select cells according to the table parts they belong to

Column names

  • Row : column-names row
  • Row # column : row-header column-name cell
  • Left columns : left column-name cell
  • Center columns : center column-name cell
  • Right columns : right column-name cell

Header section

  • Rows : header row
  • Row # : row-header header cell
  • Left columns : left header cell
  • Center columns : center header cell
  • Right columns : right header cell

Middle section

  • Rows : middle row
  • Row # : row-header middle cell
  • Left columns : left middle cell
  • Center columns : center middle cell
  • Right columns : right middle cell

Footer section

  • Rows : footer row
  • Row # : row-header footer cell
  • Left columns : left footer cell
  • Center columns : center footer cell
  • Right columns : right footer cell

For example, in order to select the cells of the last row of the center columns in the middle section, use the following selector

.ngc.middle.row .center.middle.last.cell {

All element class declarations also have the ngc class. First and last rows of each section have the resp. first and last classes. Same for cells in each row and section.
