Coming back to this, sorry. I'm trying to get the right-aligned tab stop to work and it isn't. I have the "L" facing backwards, but I see no way to set it on the ruler. What ends up happening is that when I'm typing in the input box, once I finish a line, the underlining stops at the final character instead of continuing to the edge of the table as expected.

If I hit "enter" to go down a couple of lines for separation is completely "erases" those underlined lines, leaving large blank gaps. Any suggestions?
