Often I read questions asking how to remove the gap between two \hlines
in a table, but I like the gap and want to create it in the \hline
as well, to have an equal effect for the column and row titles.
The code below makes a standard table
\documentclass{article}
\begin{document}
\begin{center}
\begin{tabular}{|c||c|c|c|}\hline
& A & B & C\\\hline\hline
A & 1 & 2 & 3\\\hline
B & 4 & 5 & 6\\\hline
C & 7 & 8 & 9\\\hline
\end{tabular}
\end{center}
\end{document}
The image shows what I am trying to accomplish.
Does a simple way to create this table exsist?
