deselectAll(_:)
Deselects all selected rows or columns if empty selection is allowed; otherwise does nothing.
Declaration

Typically the object that sent the message.

Posts selectionDidChangeNotification to the default notification center if the selection does in fact change.
As a target-action method, deselectAll(_:) checks with the delegate before changing the selection, using selectionShouldChange(in:).
