I am trying to draw arrows next to a table like this:
I was able to draw vertical arrows using the technique shown here:
$\left.
\begin{tabular}{|c|c|c|}
\hline medium & high & high \\
\hline low & medium & high \\
\hline low & low & medium \\
\hline
\end{tabular}
\right\uparrow
\rotatebox[origin=c]{90}{Impact}$
However I have no idea how to draw the horizontal arrow on top of the table. This answer seems to use the same technique to draw horizontal arrows but I was unable to adapt it. It should also be possible to use TikZ but I would like to keep it simple.
