The request concerns Table or ProTable and extending row selection to rectangular areas. Start by locating the Table/ProTable entry points and existing row-selection behavior; the issue does not name files or tests. Before implementation, clarify the selection model and the expected copy-and-paste behavior so completion can be judged.
