Currently only QTreeView supports setting viewItemPosition in QStyleOptionViewItem.
There's no reason why QTableView couln not set it to appropriate value as well, along with QListView always setting to QStyleOptionViewItem::OnlyOne.
Lack of proper support doesn't allow styles displaying, for example, border around whole row in QTableView, instead of individual cells.
