I have the following table:
\begin{tabular}{!{\color{black}\vrule}c!{\color{gray}\vrule}c!{\color{gray}\vrule}c!{\color{black}\vrule}}
\arrayrulecolor{black}\hline
& & \\
\arrayrulecolor{gray}\hline
& this one & \\
\arrayrulecolor{gray}\hline
& & \\
\arrayrulecolor{gray}\hline
\end{tabular}
Now I want to color just the lines surrounding this cell.
How can I achieve this?
Everything I was able to find related to coloring an entire horizontal or vertical line of a table.
