Description

Feature request

The table component should support Ctrl+V and Cmd+V for pasting clipboard data into cells, similar to many spreadsheet applications.

It would also be nice to export a <PasteCellsMenuItem> which does the same action. This would be used similar to <CopyCellsMenuItem> via the bodyContextMenuRenderer prop API.

Research direction
Examine the existing CopyCellsMenuItem component and the table's context menu API (bodyContextMenuRenderer) in the Blueprint source code, likely in packages/table/src/. Implement keydown event listeners for Ctrl+V/Cmd+V on the table body that read from the clipboard using navigator.clipboard.readText() and parse the data into cells. Consider handling multi cell paste by splitting on tabs and newlines. Also create a PasteCellsMenuItem component that calls the same pasting logic. Ensure the feature is tested and documented.
