How can I use tab stops and underline at the same time? I need to draw something like:
X Y Z
-----
A B C
-----
P Q R
-----
My first thought was tabbing and underline, but putting tab stops in an underline section seems to break the stops:
\begin{tabbing}
\underline{X \= Y Z} \\
\> \underline{A \= B C} \\
\> \> \underline{P \= Q R}
\end{tabbing}
Is there a way to escape the tab stops? Or just a better way altogether?
