在 2 列和多行的多个图形行中使用标题时出现问题

Question

我有一组 10*2 的图形，它们是主图形的子图形。我已经能够将它们放在我的 Latex 文档中。结果如下：

a    b
c    d
.
.
.
Figure: 1 (Caption of Figure: 1).

但我也想给每一行添加标题，并希望我的图形看起来像这样：

a    b
{Caption of first row}
.
.
.
Figure: 1 {....}

我怎样才能实现所要求的布局？

Answer 1

您可以将整个子图构造设置在里面tabular，然后将成对的标题设置为常规\multicolumn{2}{c}：

\documentclass{article}

\usepackage{graphicx,subcaption}

\begin{document}

\begin{figure}[ht]
  \begin{tabular}{c@{\quad}c}
    \subcaptionbox{first}{\includegraphics[width=.3\linewidth]{example-image-a}} &
    \subcaptionbox{second}{\includegraphics[width=.4\linewidth]{example-image-b}} \\[1.5\normalbaselineskip]
    \multicolumn{2}{c}{This is a mid-figure caption} \\[.5\normalbaselineskip]
    \subcaptionbox{third}{\includegraphics[width=.5\linewidth]{example-image-a}} &
    \subcaptionbox{fourth}{\includegraphics[width=.3\linewidth]{example-image-b}} \\[1.5\normalbaselineskip]
    \multicolumn{2}{c}{This is another mid-figure caption} \\[.5\normalbaselineskip]
    \subcaptionbox{fifth}{\includegraphics[width=.2\linewidth]{example-image-a}} &
    \subcaptionbox{sixth}{\includegraphics[width=.2\linewidth]{example-image-b}} \\[1.5\normalbaselineskip]
    \multicolumn{2}{c}{This is a final mid-figure caption} \\[.5\normalbaselineskip]
  \end{tabular}
  \caption{A figure caption}
\end{figure}

\end{document}

可以调整成对字幕和其各自子图之间的间距。
