[TableFragmentation] Paint column backgrounds correctly when fragmented.

This correctly calculates the columns-rect when fragmentation is
present. Instead of relying on the table-grid-rect - union the section
fragments of the table.

Typically this will be relatively fast, as tables typically only have
one fragment, and one section as a child of that fragment.
