I am using tabular to make simple table, I want to have double line on the sides. The problem is that the double-lines do not meet elegantly at the bottom-right corner:
How can I make the double lines meet in a better what (e.g. forming an double ell shape)?
Other environments and packages are welcomed but tabular
is preferred.
Minimal code:
\documentclass[]{article}
\usepackage{array}
\begin{document}
\begin{tabular}{c|c||}
1 & 2 \\
3 & 4 \\
\hline\hline
\end{tabular}
\end{document}
