selected is either None or the QTableItem that we want to be selected.
So if it is not None:
selected.setSelected(True) # selects the item
self.table.setCurrentItem(selected) # makes the item the current item
self.table.scrollToItem(selected) # makes the item visible to the user
In a QTableView it is possible to have a selected item that is not the
current item, in other words there are two different concepts "selected
item" and "current item".
