When multiple rows/columns are selected, the options to "Delete row" or "Delete column" do not change to "Delete rows"/"Delete columns", despite the fact that the actions do delete all selected rows/columns, and not just the "active" row or column. (IIRC, there actually once was a major table-editing program that did particularly delete only the active row/column and not all selected rows/columns, so this could be a point of confusion. Not completely sure about this.)
