dash-core-components

Added

• Added support for persistence of user-edited props to value-input components: Checklist, DatePickerRange, DatePickerSingle, Dropdown, Input, RadioItems, RangeSlider, Slider, Tabs, and Textarea. New props are persistence, persistence_type, and persisted_props. Set persistence to a truthy value to enable, the other two modify persistence behavior. See plotly/dash#903 for more details. #646

Fixed

• Fixed Slider and RangeSlider components with tooltip.always_visible #640
• Fixed an infinite loop problem when Graph is wrapped by Loading component #608

dash-renderer

Added

• #903 enables props edited by the user to persist across recreating the component or reloading the page. Components need to define three new props: persistence, persisted_props, and persistence_type as described in the lead comment of src/persistence.js. App developers then enable this behavior by, in the simplest case, setting persistence: true on the component. First use case is table, see dash-table#566

Fixed

• Reduced about 55% of the dash-renderer packages size on PyPI by removing the source maps. To do more advanced debugging, the source maps needs to be generated from source code with npm run build:local and pip install in editable mode, i.e. pip install -e . #910

dash-table

Added

#566

• Support persisting user edits when the component or the page is reloaded. New props are persistence, persistence_type, and persisted_props. Set persistence to a truthy value to enable, the other two modify persistence behavior. See plotly/dash#903 for more details.
  #319
• New 'loading_state' prop that contains information about which prop, if any, is being computed.
• Table no longer allows for editing while the data prop is loading.

Fixed

#578

• Fix #576, editing column names or deleting columns while other columns are hidden causing the hidden columns to be lost.
• Fix an unreported bug that clicking "Cancel" at the column name edit prompt would clear the name, rather than leaving it unchanged as it should.
  #569, #544
• Allow empty strings in all filter_query (e.g filter_query: '{colA} eq ""')
  #567
• Add support for missing border-radius in style_** props
• Fix table's inner vs. outer container styling
  #18
• Fix row selection vertical and horizontal alignment
  #103
• Simplify usage for multi-line cells and ellipsis. The cell's content now inherits the value of
  white-space, overflow and text-overflow from its parent, making it possible to style
  multi-line & ellipsis with style_data and other style props.
  #583
• Fix regression when editing the content of a cell in a scrolled virtualized table

Dash v1.2.0

dash

Added

• #860 Adds a new arg dev_tools_prune_errors to app.run_server and app.enable_dev_tools. Default True, tracebacks only include user code and below. Set it to False for the previous behavior showing all the Dash and Flask parts of the stack.

  This prop is read-only. Use selected_columns in callbacks instead.

#313 Ability to export table as csv or xlsx file.

#497

• New column.clearable flag that displays a "eraser" action in the column

  Clicking a merged column's "eraser" will clear all related columns.

  • Clearing column(s) will remove the appropriate data props from each datum
    row of data.
  • Additionally clearing the column will reset the filter for the affected column(s)

#318 Headers are included when copying from the table to different
tabs and elsewhere. They are ignored when copying from the table onto itself and
between two tables within the same tab.

Changed

#497 Like for clearing above, deleting through the "trash" action will also
reset the filter for the affected column(s)
