如何在 tabularx 中的多行中对齐子浮点数

Question

目前，我已经

\usepackage{subfig}
\usepackage{tabularx}
\usepackage{multirow}

\begin{figure*}
\def\tabularxcolumn#1{m{#1}}
\begin{tabularx}{\linewidth}{@{}ccc@{}}
%
\subfloat[caption]{\includegraphics[width=.3\linewidth]{a}}
\subfloat[caption]{\includegraphics[width=.3\linewidth]{b}}
\begin{tabular}{c}
\subfloat[caption]{\includegraphics[width=.25\linewidth]{c}} \\ 
\subfloat[caption]{\includegraphics[width=.25\linewidth]{d}} 
\end{tabular}
\\
\subfloat[caption]{\includegraphics[width=.3\linewidth]{e}} 
\subfloat[caption]{\includegraphics[width=.3\linewidth]{f}} 
\subfloat[caption]{\includegraphics[width=.3\linewidth]{g}} 
\\
\subfloat[caption]{\includegraphics[width=.3\linewidth]{h}} 
\subfloat[caption]{\includegraphics[width=.3\linewidth]{i}} 
\subfloat[caption]{\includegraphics[width=.3\linewidth]{j}} 

\end{tabularx}

\caption{A selection of the slides made during the user study}\label{slides}
\end{figure*}

我期待看到

但实际上，

其中 c 和 d 与 a 和 b 不对齐，导致整行更高。

我首先开始关注如何将子图放在多行中，图像按我预期的方式排列。但标题标签按列而不是行排列，如下所示

a d g/h
b e i
c f j

我尝试使用多行，但它遇到了类似的问题

\begin{tabular}{ccc}
\multirow{ 2}{*}{\subfloat[caption]{\includegraphics[width=.3\linewidth]{a}}}&
\multirow{ 2}{*}{\subfloat[caption]{\includegraphics[width=.3\linewidth]{b}} }&
\subfloat[caption]{\includegraphics[width=.25\linewidth]{c}} \\ 
&&\subfloat[caption]{\includegraphics[width=.25\linewidth]{d}} 
\end{tabular}

有没有办法将子浮点数 c 和 d 上移以匹配 a 和 b？

Answer 1

为了使图像 c 和 d 对齐，您需要将选项 [b] 添加到嵌套表中，例如：

\begin{tabular}[b]{@{}c@{}}

除此之外，你的使用tabularx也是错误的。如果你使用它，那么你也应该使用它的列类型X。图像也应该排列在列之间：

\documentclass{article}
\usepackage{graphicx}

\usepackage{subfig}
\usepackage{tabularx}
\usepackage{multirow}

\begin{document}
\begin{figure*}
\begin{tabularx}{\linewidth}{@{}*{3}{>{\centering\arraybackslash}X}@{}}
%
\subfloat[caption]{\includegraphics[width=\linewidth]{example-image-a}}
&
\subfloat[caption]{\includegraphics[width=\linewidth]{example-image-b}}
&
\begin{tabular}[b]{@{}c@{}}
\subfloat[caption]{\includegraphics[width=.8\linewidth,height=1cm]{example-image}} \\
\subfloat[caption]{\includegraphics[width=.8\linewidth,height=1cm]{example-image}}
\end{tabular}
\\
\subfloat[caption]{\includegraphics[width=\linewidth]{example-image}}
&
\subfloat[caption]{\includegraphics[width=\linewidth]{example-image}}
&
\subfloat[caption]{\includegraphics[width=\linewidth]{example-image}}
\\
\subfloat[caption]{\includegraphics[width=\linewidth]{example-image}}
&
\subfloat[caption]{\includegraphics[width=\linewidth]{example-image}}
&
\subfloat[caption]{\includegraphics[width=\linewidth]{example-image}}
\end{tabularx}

Answer 2

你不需要任何外部tabular（甚至更少tabularx）。

\documentclass{article}
\usepackage{graphicx}

\usepackage{subfig}

\begin{document}

\begin{figure}[htp]

\subfloat[caption]{\includegraphics[width=.3\textwidth]{example-image-a}}\hfill
\subfloat[caption]{\includegraphics[width=.3\textwidth]{example-image-b}}\hfill
\begin{minipage}[b]{.3\textwidth}
\subfloat[caption]{\includegraphics[width=\textwidth,height=1cm]{example-image}} \\
\subfloat[caption]{\includegraphics[width=\textwidth,height=1cm]{example-image}}
\end{minipage}

\subfloat[caption]{\includegraphics[width=.3\textwidth]{example-image}}\hfill
\subfloat[caption]{\includegraphics[width=.3\textwidth]{example-image}}\hfill
\subfloat[caption]{\includegraphics[width=.3\textwidth]{example-image}}

\subfloat[caption]{\includegraphics[width=.3\textwidth]{example-image}}\hfill
\subfloat[caption]{\includegraphics[width=.3\textwidth]{example-image}}\hfill
\subfloat[caption]{\includegraphics[width=.3\textwidth]{example-image}}

\end{figure}
\end{document}

诀窍是使用合适的宽度，即略小于文本宽度的 1/3。

\documentclass{article}
\usepackage{graphicx}

\usepackage{subfig}

\begin{document}

\begin{figure}[htp]

\subfloat[caption]{\includegraphics[width=.3\textwidth]{example-image-a}}\hfill
\subfloat[caption]{\includegraphics[width=.3\textwidth]{example-image-b}}\hfill
\begin{minipage}[b]{.3\textwidth}
\subfloat[caption]{\includegraphics[width=\textwidth,height=1cm]{example-image}} \\
\subfloat[caption]{\includegraphics[width=\textwidth,height=1cm]{example-image}}
\end{minipage}

\subfloat[caption]{\includegraphics[width=.3\textwidth]{example-image}}\hfill
\subfloat[caption]{\includegraphics[width=.3\textwidth]{example-image}}\hfill
\subfloat[caption]{\includegraphics[width=.3\textwidth]{example-image}}

\subfloat[caption]{\includegraphics[width=.3\textwidth]{example-image}}\hfill
\subfloat[caption]{\includegraphics[width=.3\textwidth]{example-image}}\hfill
\subfloat[caption]{\includegraphics[width=.3\textwidth]{example-image}}

\end{document}

如果您没有subfig因为特定原因而受限于不兼容的文档类caption，我建议caption与一起使用subcaption。

\documentclass{article}
\usepackage{graphicx}

\usepackage{caption,subcaption}

\begin{document}

\begin{figure}[htp]

\subcaptionbox{caption}{\includegraphics[width=.3\textwidth]{example-image-a}}\hfill
\subcaptionbox{caption}{\includegraphics[width=.3\textwidth]{example-image-b}}\hfill
\begin{minipage}[b]{.3\textwidth}
\subcaptionbox{caption}{\includegraphics[width=\textwidth,height=1cm]{example-image}}\\[1ex]
\subcaptionbox{caption}{\includegraphics[width=\textwidth,height=1cm]{example-image}}
\end{minipage}

\medskip

\subcaptionbox{caption}{\includegraphics[width=.3\textwidth]{example-image}}\hfill
\subcaptionbox{caption}{\includegraphics[width=.3\textwidth]{example-image}}\hfill
\subcaptionbox{caption}{\includegraphics[width=.3\textwidth]{example-image}}

\medskip

\subcaptionbox{caption}{\includegraphics[width=.3\textwidth]{example-image}}\hfill
\subcaptionbox{caption}{\includegraphics[width=.3\textwidth]{example-image}}\hfill
\subcaptionbox{caption}{\includegraphics[width=.3\textwidth]{example-image}}
