Use this layout style to present a closed sub-variable's screen as a vertical question table. For example:

To do so, select all the sub-variable's cells, go to the layout menu, select styles and then vertical question table.
As this layout is intended for a loop's sub-variable's screens, it will activate the Sub-form property of the screen. Furthermore it will appropriately apply the cell's Sub-form position properties. The response item cells will be divided in two, one cell containing the item’s caption, the other cell containing its corresponding Radio button or Tick box. Lastly, a new cell is created containing the call to the loop’s items, using the ?? tag.
