[Table Improvement] Add column resizing support to the new ui5-table

[adhamelgindy]

The new ui5-table (v2+) is missing column resizing, a feature that was available in the previous version.

Users should be able to resize columns by dragging the column borders, ideally through a resizable property on ui5-table-header-cell.

This is a common table feature, and a native UI5 implementation would be greatly appreciated.

Hello @UI5/ui5-team-tbl ,

The user would want to be able to resize the columns inside the table. Currently this is not possible.

Could you please see if the request is feasible to implement?

Plamen Ivanov
