- *

- *
- * Setting the table selection start in table cell "b" and the end in table cell "g" will select table cells: "b", "c", "d", "f", and "g".
- * The cells that span over multiple rows or columns can extend over the selection rectangle. For instance, setting a selection from
- * the table cell "a" to the table cell "i" will create a selection in which the table cell "i" will be (partially) outside
- * the rectangle of selected cells: "a", "b", "e", "f", "h", and "i".
