調整 subfloatrow 標題中的垂直間距 (subcaption+floatrow)

Question

我正在嘗試調整圖中子圖的子標題，其中包括多個s 和行外的\subfloatrow附加內容。\ffigbox

如何修改子圖和子標題之間以及子標題與其下面的任何子圖之間的垂直間距？我希望子標題更接近其子圖，並且離其下面的任何子圖稍遠。

代碼：

\documentclass{article}
\usepackage{graphicx}
\usepackage{subcaption}
\usepackage[valign=c,heightadjust=all]{floatrow}
\begin{document}
\begin{figure}
  \centering
  \captionsetup[subfloatrow]{font+={footnotesize}}%
  \floatbox{figure}{%
    \begin{subfloatrow}[2]
      \ffigbox[\FBwidth]{%
        \includegraphics[height=8em]{example-image-a}}{\caption*{Sub-Caption}}
      \ffigbox[\FBwidth]{%
        \includegraphics[height=8em]{example-image-a}}{\caption*{Sub-Caption}}
    \end{subfloatrow}

    \begin{subfloatrow}[3]
      \ffigbox[\FBwidth]{%
        \includegraphics[height=8em]{example-image-a}}{\caption*{Sub-Caption}}
      \ffigbox[\FBwidth]{%
        \includegraphics[height=8em]{example-image-a}}{\caption*{Sub-Caption}}
      \ffigbox[\FBwidth]{%
        \includegraphics[height=8em]{example-image-a}}{\caption*{Sub-Caption}}
    \end{subfloatrow}

    \begin{subfloatrow}[3]
      \ffigbox[\FBwidth]{%
        \includegraphics[height=8em]{example-image-a}}{\caption*{Sub-Caption}}
      \ffigbox[\FBwidth]{%
        \includegraphics[height=8em]{example-image-a}}{\caption*{Sub-Caption}}
      \ffigbox[\FBwidth]{%
        \includegraphics[height=8em]{example-image-a}}{\caption*{Sub-Caption}}
    \end{subfloatrow}

    \begin{subfloatrow}[2]
      \ffigbox[\FBwidth]{%
        \includegraphics[height=8em]{example-image-a}}{\caption*{Sub-Caption}}
      \ffigbox[\FBwidth]{%
        \includegraphics[height=8em]{example-image-a}}{\caption*{Sub-Caption}}
    \end{subfloatrow}

    \ffigbox{%
      \includegraphics[height=8em]{example-image-a}}{\subcaption*{Sub-Caption}}
  }{%
    \caption{Caption}\label{fig:label}%
  }
\end{figure}
\end{document}

岡特拉姆的問題類似，但是2年多了還沒有答案。評論中的建議是放棄使用floatrow.但是，我認為這應該與caption/subcaption包一起使用。至少，文檔是這麼說的。

然而，我發現floatrow的文檔一點也不簡單，而且我無法真正弄清楚caption- subcaption-floatrow是如何很好地協同工作的。

控制行之間的垂直間距很好地隱藏在文件中：您必須透過 宣告一個鍵\DeclareFloatVCode，並要求使用 來套用它\floatsetup{rowpostcode= …}。可以透過 更改字體大小\captionsetup[subfigure]，並透過 解決圖形和標題之間的垂直跳躍\floatsetup{captionskip= …}。

這是一個（可怕的）例子：

\documentclass{article}
\usepackage[showframe, margin=25mm]{geometry}
\usepackage{graphicx}
\usepackage{subcaption}
\usepackage[,heightadjust=all]{floatrow}

\DeclareFloatVCode{largevskip}%
{\vskip 20pt}
\floatsetup{captionskip=0pt,rowpostcode =largevskip, valign=c }%
\captionsetup[subfigure]{font =Large}

\begin{document}
\begin{figure}
  \centering-%
  \floatbox{figure}{%
    \begin{subfloatrow}[2]
      \ffigbox[\FBwidth]{%
        \includegraphics[height=8em]{example-image-a}}{\caption*{Sub-Caption}}
      \ffigbox[\FBwidth]{%
        \includegraphics[height=8em]{example-image-a}}{\caption*{Sub-Caption}}
    \end{subfloatrow}

    \begin{subfloatrow}[3]
      \ffigbox[\FBwidth]{%
        \includegraphics[height=8em]{example-image-a}}{\caption*{Sub-Caption}}
      \ffigbox[\FBwidth]{%
        \includegraphics[height=8em]{example-image-a}}{\caption*{Sub-Caption}}
      \ffigbox[\FBwidth]{%
        \includegraphics[height=8em]{example-image-a}}{\caption*{Sub-Caption}}
    \end{subfloatrow}

    \begin{subfloatrow}[3]
      \ffigbox[\FBwidth]{%
        \includegraphics[height=8em]{example-image-a}}{\caption*{Sub-Caption}}
      \ffigbox[\FBwidth]{%
        \includegraphics[height=8em]{example-image-a}}{\caption*{Sub-Caption}}
      \ffigbox[\FBwidth]{%
        \includegraphics[height=8em]{example-image-a}}{\caption*{Sub-Caption}}
    \end{subfloatrow}

    \begin{subfloatrow}[2]
      \ffigbox[\FBwidth]{%
        \includegraphics[height=8em]{example-image-a}}{\caption*{Sub-Caption}}
      \ffigbox[\FBwidth]{%
        \includegraphics[height=8em]{example-image-a}}{\caption*{Sub-Caption}}
    \end{subfloatrow}

    \ffigbox{%
      \includegraphics[height=8em]{example-image-a}}{\subcaption*{Sub-Caption}}
  }{%
    \caption{Caption}\label{fig:label}%
  }
\end{figure}
