详细描述

The QTableWidgetSelectionRange class stores the top left and bottom right rows and columns of a selection range in a table. The selections in the table may consist of several selection ranges.

注意: If the item within the selection range is marked as not selectable, e.g., itemFlags() & Qt::ItemIsSelectable == 0 then it will not appear in the selection range.
