This will seem like a simple question, but how do you put a line across the page when your page is set up to be two columns? When I use the tool (in Gatekeeper) to put a line in, it only puts it in the first column.
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.
