Grid: Support for defining column widths via CSS has been removed.
UPGRADE NOTESEXPANDCOLLAPSE
Important Notice to Dashboards users:Datagrid is now Grid Pro and no longer part of the Dashboards package. To use Grid Pro as a standalone component, you need to import it from an external library - either Grid Pro or Grid Lite. See the Migration Guide for more details.
The old column distribution modes (full, fixed, mixed) have been replaced with new column resizing modes (adjacent, independent, distributed).
The previously deprecated rendering.columns.distribution option has been removed. To configure column resizing, use the new rendering.columns.resizing.mode option.
If you used the resizing property in column definitions, move this logic to rendering.columns.resizing.enabled at the appropriate level.
Review your project for any CSS rules targeting column widths and migrate those settings to the grid configuration options.
