It calls TableCellPainter::paintContainerBackgroundBehindCell() after setting up
the paint offset in LayoutTableRow's specific way.

I could move this into TableCellPainter
(TableCellPainter::paintRowBackgroundBehindCell()) but it seems better to put it
here because it contains LayoutTableRow-specific code.

 
 private:
     const LayoutTableRow& m_layoutTableRow;
