带有子标题包的真实脚注

Question

我想在段落标题中添加一些脚注subcaption。但是，正如您所见，脚注节点出现在标题本身中，而不是页面底部。

有什么解决办法吗？

谢谢！

Answer 1

您可以使用\footnotemarkand\footnotetext对：

\documentclass{article}
\usepackage{graphicx}
% To display subfigures
\usepackage{caption}
\usepackage{subcaption}

\begin{document}
\begin{figure}[h!]
  \centering
  \begin{subfigure}[t]{.47\textwidth}
    \centering
    \includegraphics[width=\linewidth]{example-image-a}
    \caption{My caption with a footnote\protect\footnotemark}
    \label{fig:myfiga}
  \end{subfigure}\hspace*{.05\textwidth}%
  \begin{subfigure}[t]{.47\textwidth}
    \centering
    \includegraphics[width=\linewidth]{example-image-b}
    \caption{Other caption}
    \label{fig:myfigb}
  \end{subfigure}
  \caption{My big caption}
  \label{fig:myfig}
\end{figure}
\footnotetext{Yes I like footnotes ! But this one is not a true foot note, because it's not at the bottom of the page...}
\end{document}

或者，如果您更喜欢更自动化的解决方案（至少需要 LaTeX 2020-10-01），您可以\footnote在环境中重新定义figure，以便它执行\footnotemark，并将存储在环境\footnotetext之后执行的钩子中figure，然后您只需\footnote在里面使用即可figure：

\documentclass{article}
\usepackage{graphicx}
% To display subfigures
\usepackage{caption}
\usepackage{subcaption}

\AddToHook{env/figure/begin}{%
  \DeclareRobustCommand\footnote[1]{%
    \footnotemark
    \expanded{\AddToHookNext{env/figure/after}%
      {\noexpand\setcounter{footnote}{\thefootnote}%
       \noexpand\footnotetext\unexpanded{{#1}}}}}}

\begin{document}
\begin{figure}[h!]
  \centering
  \begin{subfigure}[t]{.47\textwidth}
    \centering
    \includegraphics[width=\linewidth]{example-image-a}
    \caption{My caption with a footnote\footnote
      {Yes I like footnotes ! But this one is not a true foot note,
        because it's not at the bottom of the page...}}
    \label{fig:myfiga}
  \end{subfigure}\hspace*{.05\textwidth}%
  \begin{subfigure}[t]{.47\textwidth}
    \centering
    \includegraphics[width=\linewidth]{example-image-b}
    \caption{Other caption\footnote{Another}}
    \label{fig:myfigb}
  \end{subfigure}
  \caption{My big caption\footnote{MOAR}}
  \label{fig:myfig}
\end{figure}
\end{document}

Answer 2

FWIW，我有一个类似的用例，但我想在父图正下方显示从子图生成的所有脚注。为了实现这一点，我调整了Phelype 的解决方案从上面（需要 LaTeX 2020-10-01 或更高版本）：

\usepackage{footmisc}
\AddToHook{env/subfigure/begin}{%
    \DeclareRobustCommand\footnote[1]{%
        \mpfootnotemark
        \expanded{\AddToHookNext{env/subfigure/after}%
            {\noexpand\setcounter{mpfootnote}{\arabic{mpfootnote}}%
             \noexpand\footnotetext\unexpanded{{#1}}}}}}
