How to render (resize) the table on column resize end ?

Current behaviour: The table renders alongwith the column resize line without any debouncing.
Desired behaviour: Resize / re-render the table only on resize end and until then just show the resize line placeholder.

Is this achievable ?

No files, tests, or entry points are named. Start by locating the table's column-resize handling and rendering path, then trace how resizing updates the resize line and table. Done means the table re-renders only after resizing ends while the resize-line placeholder remains visible during the interaction, with tests covering that behavior.
