乳胶桌中的一条水平线

Question

I want to put a horizontal line between first and second rows in the following table:

\begin{table}[ht]
    \centering
    \caption{Multi-row table}
    \label{tab:Mergedrows}
    \vspace{1ex}
        \begin{tabular}{|c|c|}
            \hline
            \multirow{2}{*}{Mergedrows}
            &X\\
            &X \\
            \hline
        \end{tabular}
\end{table}

How to do this?

Answer 1

Just like the documentation to multirow shows: by adding a cline :

\documentclass{article}
\usepackage{multirow}

\begin{document}
\begin{table}[ht]
    \centering
    \caption{Multi-row table}
    \label{tab:Mergedrows}
    \vspace{1ex}
        \begin{tabular}{|c|c|}
            \hline
            \multirow{2}{*}{Mergedrows}
            &X\\
            \cline{2-2} % add this
            &X \\
            \hline
        \end{tabular}
\end{table}
\end{document}
