The QTableWidgetSelectionRange class provides a way to interact with selection in a model without using model indexes and a selection model.
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.
