将图表放在表格内，并为每个图表添加标题

Question

我尝试在表格中放置 2 x 2 的数字，每个数字都有标题

我试过

\begin{table}[ht]
\begin{tabular}{cc}
\begin{subfigure}\centering\includegraphics[width=0.3\columnwidth]{./img/1.png}\caption{Figure A}\label{fig:taba}\end{subfigure}&
\begin{subfigure}\centering\includegraphics[width=0.3\columnwidth]{./img/1.png}\caption{Figure B}\label{fig:tabb}\end{subfigure}\\
\newline
\begin{subfigure}\centering\includegraphics[width=0.3\columnwidth]{./img/1.png}\caption{Figure C}\label{fig:tabc}\end{subfigure}&
\begin{subfigure}\centering\includegraphics[width=0.3\columnwidth]{./img/1.png}\caption{Figure A again}\label{fig:taba2}\end{subfigure}\\
\end{tabular}
\caption{A table with figures}
\label{tab:mytable}
\end{table}

但这会产生错误

[109] [110] <use ./img/1.png>
! You can't use `\hrule' here except with leaders.
\caption@hrule ->\hrule 
                        \@height \z@ 
l.888 ...nwidth]{./img/1.png}\caption{Figure A}
                                                  \label{fig:taba}\end{subfi...

有人能帮忙解决吗？我检查了很多代码块来将数字放在表格中，但都没有用

我猜你想获得这样的东西：

\documentclass{article}
\usepackage[demo]{graphicx}
\usepackage{tabularx}
\usepackage[skip=1ex]{caption}

\begin{document}
    \begin{table}[ht]
    \centering
\begin{tabularx}{\columnwidth}{XX}
\includegraphics[width=\linewidth]{./img/1.png}
\captionof{figure}{Figure A}\label{fig:taba}
    &   \includegraphics[width=\linewidth]{./img/1.png}   
        \captionof{figure}{Figure B}\label{fig:tabb}              \\
\includegraphics[width=0.45\columnwidth]{./img/1.png}
\captionof{figure}{Figure C}\label{fig:tabc}
    &   \includegraphics[width=\linewidth]{./img/1.png} 
        \captionof{figure}{Figure D}\label{fig:tabd}               
\end{tabularx}
\caption{A table with figures}
\label{tab:mytable}
    \end{table}%
\end{document} 

或者将图形作为子图形？

\documentclass{article}
\usepackage[demo]{graphicx}
\usepackage[skip=1ex]{caption}
\usepackage{subcaption}

\begin{document}
    \begin{table}[ht]
\begin{subfigure}{0.45\columnwidth}
\includegraphics[width=\linewidth]{./img/1.png}
    \caption{figure}\label{fig:taba}
\end{subfigure}\hfill
\begin{subfigure}{0.45\columnwidth}
\includegraphics[width=\linewidth]{./img/1.png}   
    \caption{Figure B}\label{fig:tabb}             
\end{subfigure}\\[1em]
%
\begin{subfigure}{0.45\columnwidth}
\includegraphics[width=\linewidth]{./img/1.png}
    \caption{Figure C}\label{fig:tabc}
\end{subfigure}\hfill
\begin{subfigure}{0.45\columnwidth}
\includegraphics[width=\linewidth]{./img/1.png} 
    \caption{Figure D}\label{fig:tabd}               
\end{subfigure}
\caption{A table with figures}
\label{tab:mytable}
    \end{table}%
\end{document}
