对齐子浮动标题

Question

我遇到了子浮点数标题的对齐问题。示例如下：

\documentclass{article}
\usepackage{subfig}
\usepackage{graphicx}

\begin{document}

\begin{figure}[htb]
\captionsetup[subfloat]{farskip=2pt,captionskip=1pt}
\centering

\subfloat[caption 2]{
    \begin{minipage}{0.30\columnwidth}
    \includegraphics[width=0.45\textwidth]{example-image-a}\\
    \includegraphics[width=0.45\textwidth]{example-image-b}
    \includegraphics[width=0.45\textwidth]{example-image-c}\\
    \end{minipage}

}
\subfloat[caption 2]{\includegraphics[width=0.48\textwidth]{example-image}}

\caption{There are example figures}
\end{figure}
\end{document}

结果是：

我们如何才能对齐（a）和（b）的标题？

Answer 1

其中一个minipage会使图像定位混乱（由于它的基线）。解决方案是使用两个或代替它们使用，tabular如下例所示：

\documentclass{article}
\usepackage{subfig}
\usepackage{graphicx}
\usepackage{array,calc}
\begin{document}

    \begin{figure}[htb]
\captionsetup[subfloat]{farskip=2pt,captionskip=1pt}
    \begin{tabular}{*{2}{b{0.5\textwidth-2\tabcolsep}}}
\includegraphics[width=0.48\hsize]{example-image-a}}

\subfloat[caption 1]{\includegraphics[width=0.48\hsize]{example-image-b}
\hfill
                     \includegraphics[width=0.48\hsize]{example-image-c}
}
    &
\subfloat[caption 2]{
    \includegraphics[width=0.96\hsize]{example-image}}
\end{tabular}
\caption{There are example figures}
    \end{figure}
\end{document}
