I have a table as in the figure and code below. The problem is that it really hard to see that the cells 22-34 belongs to the multirow R-23. I would like to reduce the row spacing for these to rows to bring them close to each other. How would I do that?
Preferably it is a global setting that reduces the row spacing for all multi-rows.
\begin{tabular}{*4l}\toprule
\textbf{R1} & 12 & 13 & 14 \\
\multirow{2}{*}{\textbf{R2-3}} & 22 & 23 & 24 \\
& 32 & 33 & 34 \\
\textbf{R4} & 42 & 43 & 44 \\
\bottomrule
\end{tabular}
