In QAccessibleTable's model, cells (rather than rows or columns)
are direct children of the table and therefore items handled in
the selection, so forward/make use of the corresponding methods
that handle cells.
(In QAccessibleTable::select and QAccessibleTable::unselect,
cast the child cell to QAccessibleTableCell*, as is already
done in QAccessibleTable::indexOfChild and
QAccessibleTree::indexOfChild.)
This can be tested e.g. by calling the methods from the
AT-SPI Selection interface using Accerciser and the
"interview" example
(qtbase/examples/widgets/itemviews/interview/interview).
