向两个并排的表格添加标签

Question

我把两张桌子并排放置，但是无法正确放置标签。

\begin{table}[ht]
\begin{minipage}[b]{0.45\linewidth}\centering
\begin{tabular} {l | l | l}
        a & a & a
        \end{tabular}
        \label{tab:NotreDame}
        \caption{Training on Yosemite dataset and testing on Notre-Dame dataset}
        \end{minipage}
\hspace{0.5cm}
\begin{minipage}[b]{0.45\linewidth}
\centering
    \begin{tabular} {l | l | l}
        b & b & b
        \end{tabular}
        \label{tab:Liberty}
        \caption{Training on Yosemite dataset and testing on Liberty dataset}
\end{minipage}
\end{table}

当我编译我的代码时，我得到的是问号而不是正确的引用。

Answer 1

除了把 放在标题后面外，把 放在 里面label也可以。labelcaption

代码：

\documentclass{article}
\usepackage[demo]{graphicx} % for inclusion of graphics

\begin{document}

\begin{table}[ht]
\begin{minipage}[b]{0.45\linewidth}
\centering
\begin{tabular} {l | l | l}
        a & a & a
        \end{tabular}
        \caption{Training on Yosemite dataset and testing on Notre-Dame dataset}
       \label{tab:NotreDame}
        \end{minipage}
\hspace{0.5cm}
\begin{minipage}[b]{0.45\linewidth}
\centering
    \begin{tabular} {l | l | l}
        b & b & b
        \end{tabular}
        \caption{Training on Yosemite dataset and testing on Liberty dataset \label{tab:Liberty} }
\end{minipage}
\end{table}

This is Table \ref{tab:NotreDame} and Table \ref{tab:Liberty}

\end{document}
