Description
Describe the bug
When using the <Column />'s sortable property in combination with editor and any editMode in <DataTable />, the editor sometimes displays an outdated value momentarily after sorting the rows.
This issue is less noticeable with smaller tables but becomes increasingly apparent as the number of elements grow.

Done means the configured editor always displays the current cell value after rows are sorted.
