Infinite Table React DataGrid version 3.0.0 released

By admin·

Version 3.0.0 is a release that brings a long awaited feature: cell selection. This allows the user to perform fined-grained cell selection, either via the cellSelection prop or via the Cell Selection API.

Version 3.0.0 highlights 🎉

1️⃣ support for single and multiple cell selection 2️⃣ cell selection using wildcards 3️⃣ cell selection API

1️⃣ Support for single and multiple cell selection#

It's been a long-requested feature to implement cell selection.
We knew we needed to implement it, but we wanted to do it right while keeping it easy to understand.
In fact, we prepared some things in advance - namely selectionMode was there, it just needed to accept a new value: "multi-cell".
Configuring multi-cell selection
<DataSource<Developer>
  selectionMode="multi-cell" // <--- THIS
  primaryKey="id"
  data={[...]}
The line above is all you need to do to enable cell selection. This allows the user to Click or Cmd/Ctrl+Click to select a specific cell and Shift+Click to select a range of cells. It's exactly the behavior you'd expect from a spreadsheet application.
Try Cmd/Ctrl+Clicking in the DataGrid cells below to see multiple cell selection in action.
SelectionMode set to 'multi-cell' to allow cell selection

Using a default selection#

If you want to render the DataGrid with a default selection, you can use the defaultCellSelection prop.
const defaultCellSelection = {
  defaultSelection: false,
  selectedCells: [
    [3, 'hobby'],
    [4, 'firstName'],
    [4, 'hobby'],
    [4, 'preferredLanguage'],
    [4, 'salary'],
  ],
};
The format for the uncontrolled defaultCellSelection (and also for the controlled cellSelection) is an object with two properties:
  • defaultSelection - boolean - whether or not cells are selected by default.
  • and either
    • selectedCells - [string|number, string][] - only needed when defaultSelection is false
  • or
    • deselectedCells - [string|number, string][] - only needed when defaultSelection is true
The value for selectedCells and deselectedCells should be an array of [rowId, colId] tuples.
The rowId is the id of the row (the primary key), and the colId is the id of the column (the identifier of the column in the columns prop).
This object shape for the defaultCellSelection/cellSelection props allows you full flexibility in specifying the selection. You can specify a single cell, a range of cells, or even a non-contiguous selection. You can default to everything being selected, or everything being deselected and then enumerate your specific exceptions.

2️⃣ Cell Selection using wildcards#

The above examples show how to select specific cells, but what if you want to select all cells in a column, or all cells in a row?
Well, that turns out to be straightforward as well. You can use the * wildcard to select all cells in a column or all cells in a row.
All cells in row with id rowId3 and all cells in hobby column are selected
const defaultCellSelection = {
  defaultSelection: false,
  selectedCells: [
    ['*', 'hobby'],
    ['rowId3', '*'],
  ],
}
<DataSource selectionMode="multi-cell" defaultCellSelection={defaultCellSelection} />
Cell selection using wildcards
Wildcard selection is really powerful and it allows you to select lots of cells without the need to enumerate them all.
For example, you can easily select all cells except a few.

Listening to selection changes#

You can listen to selection changes by using the onCellSelectionChange prop.
If you're using controlled cell selection, you have to update the cellSelection prop yourself in response to user interaction - so onCellSelectionChange will be your way of listening to selection changes.

3️⃣ Cell Selection API#

In addition to managing cell selection declaratively, which we encourage, you can also use the Cell Selection API to imperatively update the current selection.
We offer the following methods:
  • selectCell - selects a single cell, while allowing you to keep or to clear previous selection
  • deselectCell - deselects the specified cell
  • selectColumn - selects a whole column in the DataGrid
  • deselectColumn - deselects the specified column
  • selectRange - selects a range of cells
  • deselectRange - deselects the specified range of cells
  • selectAll - selects all cells in the DataGrid
  • clear - clears selection (deselects all cells in the DataGrid)
  • isCellSelected - checks if the specified cell is selected or not
