When MultiSelect is set to true, multiple rows can be selected by pressing Shift+Click or Ctrl+Click one at a time. If I have to select say, 5, 0r 10 rows, I have click as many times as the number of rows I want to select.
For contiguous rows, wouldn’t it be nice that once we click a rowheader, we can drag the mouse up or down the row headers to make a multiple rows selection? Same with adjacent cells.
Just my 2 cents.
