回忆录如何打印内容页的标题？

关于这个问题如何动态计算空列表的高度？，我了解到我需要知道我的班级如何计算其内容页面标题，以便使答案有效。我试过\large\contentsname\vskip\baselineskip\vskip\afterchapskip，但这还不够，因为List of Tables是空的（没有表格）并且不应该显示：

我如何设置\boxBforwhenlistisnotempty回忆录标题页？

\documentclass[12pt,a4paper]{memoir}

\newbox\boxAforwhenlistisnotempty
\newbox\boxBforwhenlistisnotempty

\newcommand{\whenlistisnotempty}[2]{%
  \setbox\boxAforwhenlistisnotempty\vbox{#2}%
  \setbox\boxBforwhenlistisnotempty\vbox{%
    \large\contentsname\vskip\baselineskip\vskip\afterchapskip%
  }%
  \typeout{The height of the list '#1'
      is '\the\ht\boxAforwhenlistisnotempty'
      from '\the\ht\boxBforwhenlistisnotempty'}%
  \ifdim\ht\boxAforwhenlistisnotempty>\ht\boxBforwhenlistisnotempty%
    \unvbox\boxAforwhenlistisnotempty%
  \fi%
}

\begin{document}
\tableofcontents

\whenlistisnotempty{\listfigurename}{
\listoffigures
}

\whenlistisnotempty{\listtablename}{
\listoftables
}

\chapter{First section}

\begin{figure}
    \centering

    \caption{Caption}
\end{figure}

\end{document}

答案1

虽然这不是答案，但这可能会有所帮助。

如果您调用，\listoftables则.lot文件将被创建。\chapter命令将添加

\addvspace{10pt}

到文件和表格标题将添加类似

\contentsline{table}{\numberline}{1.1}{\ignorespaces A table}}{3}%

到文件。

如果没有表格，则.lot文件将仅包含\addvspace{10pt}
