      # Account for the fact that some columns will have more screen rows than their
      # counterparts in the row.  An example being:
      # c1 = Column.new('x' * 50, width: 10)
      # c2 = Column.new('x' * 20, width: 10)
      #

      # c2.screen_rows.size == 2
      #
      # So when we don't have a screen row for c2 we need to fill the screen with the
      # proper number of blanks so the layout looks like (parenthesis on the right just
      # indicate screen row index)
