I'm trying to draw a double horizontal line with longtabu
\begin{longtabu}{|l |l |}
\hline
0 & 1\\
\hline \hline
1 & 0\\
\hline
\end{longtabu}
... however, all I get is a thick line.
When using tabu
, everything works as expected.
How should I proceed so as to get a double horizontal line using longtabu
?
