如何在这个网格格式中定位图形（见图）？对齐问题

Question

我想按以下格式定位 4 个数字：

我试过

\documentclass{book}
\usepackage{multirow}
\usepackage{graphicx}
\begin{document}

    \begin{figure}
    \begin{tabular}{c c c}
    \multirow{2}{2cm}{\includegraphics[scale=1]{test} } & \multirow{2}{4cm}{\includegraphics[scale=1]{test}} & \includegraphics[scale=1]{test2} \\ 

    & & \includegraphics[scale=1]{test2} \\

\end{document}

但我得到的结果是：

我该如何对齐这些数字？

Answer 1

tabulars 可以嵌套

\documentclass{article}

\usepackage{graphicx,array}

\begin{document}

\begin{figure}
\centering
\begin{tabular}{*{3}{m{1.2cm}}}
\includegraphics[width=1cm,height=2cm]{example-image} &
\includegraphics[width=1cm,height=2cm]{example-image} &
\begin{tabular}[b]{@{}c@{}}
\includegraphics[width=1cm,height=1cm]{example-image}  \\ \includegraphics[width=1cm,height=1cm]{example-image} \end{tabular}
\end{tabular}
\caption{Caption}
\end{figure}

\end{document}

当然，如果高度必须相同，那么还有很多工作要做

\documentclass{article}

\usepackage{graphicx}

\begin{document}


\begin{figure}
\centering
\parbox[][2.5cm][c]{1cm}{\includegraphics[width=1cm,height=2.5cm]{example-image}}
\parbox[][2.5cm][c]{1cm}{\includegraphics[width=1cm,height=2.5cm]{example-image}}
\parbox[][2.5cm][c]{1cm}{\includegraphics[width=1cm,height=1cm]{example-image}\par\vfill\includegraphics[width=1cm,height=1cm]{example-image}}
\caption{Caption}
\end{figure}


\end{document}
