Discontinuous line using \multirow

Question

I've been struggling with table editing, so I started using a website to generate tables in LaTeX. However, whenever I'm using multirow and borders, things get a little tricky. I get a discontinuous line along my column.

As a test, I'm using this:

\begin{table}[]
\centering
\caption{My caption}
\label{my-label}
\begin{tabular}{@{}c|cc@{}}
Test               & a & b \\ \midrule
\multirow{2}{*}{x} & 1 & 2 \\ \cmidrule(l){2-3} 
               & 3 & 4
\end{tabular}
\end{table}

This is the result:

I'm using TexPortable with MiKTeX 2.9.6210 and Texmaker 4.5.

This is related to the padding around horizontal lines in booktabs (the lengths \aboverulesep and \belowrulesep). Vertical rules should not be used with booktabs in general (this principle suffers exceptions). A workaround consists in setting them to 0 and replacing them with more or less equivalent lengths added at the top and bottom of cells with the tools from makecell.

\documentclass{article}
\usepackage{booktabs, multirow, array, makecell, caption}

\begin{document}

\begin{table}[!htb]
\centering
\setlength\aboverulesep{0pt}\setlength\belowrulesep{0pt}
\setcellgapes{3pt}\makegapedcells
\caption{My caption}
\label{my-label}
\begin{tabular}{@{}c|cc@{}}
Test & a & b \\ \midrule
\multirow{2}{*}{x} & 1 & 2 \\ \addlinespace[-0.03em]\cmidrule(l){2-3}
               & 3 & 4
\end{tabular}
\end{table}

\end{document}

I've tried that and it worked on the vertical line, but the horizontal line is still discontinuous, here. Thank you! – This Guy Apr 26 '17 at 09:18

Do you mean the short line between 2nd and 3rd row? I thought it was there purposely. The responsible is the (l) optional argument of \cmidrule. Just remove it. – Bernard Apr 26 '17 at 09:25

If you want vertical lines compatible with the horizontal rules of booktabs, you should use {NiceTabular} of nicematrix.

\documentclass{article}
\usepackage{booktabs, caption, nicematrix}
\begin{document}
\begin{table}[!htb]
\centering
\caption{My caption}
\label{my-label}
\begin{NiceTabular}{@{}c|cc@{}}[cell-space-limits=3pt]
Test & a & b \ \midrule
\Block{2-1}{x} & 1 & 2 \ \cmidrule(l){2-3}
               & 3 & 4
\end{NiceTabular}
\end{table}
\end{document}
