Nothing. This is the default.

The default is to allow multiple cells to be selected at the same time:

* click on cell: select this cell
* click on row header: select the entire row
* click on column header: select the entire column
* no meta keys pressed at that time: deselect current selection and make fresh 
* Shift pressed: make it a range selection spanning from the last selected 
cell to the new one
* Ctrl pressed: add to the existing selection

Chose a different selection behavior, see QAbstractItemView::SelectionBehavior 
and ...::SelectionMode for details.

The default is a Behavior of SelectItems and a Mode of ExtendedSelection
