If the page is 2 solid columns down the page, putting a solid line across both cells isn't possible that way as all you did was draw a line across one table cell. A simple way to do this would be to make a new row that spans both columns and draw a line in that single cell spanning the columns.

Maybe someone else has a better idea, but that should work.
