Paint background invalidation when deleting the last element of TableRow

When the last element in a TableRow is deleted, it does not trigger
a redraw of the background,causing the background to persist.
After removing the last element of a row in a Table,
the size of the TableRow remains unchanged because it does not affect
the layout of the preceding elements.
Therefore, caching is used during rendering.
We should proactively trigger a redraw of this row when deleting
the last element of a table row.
