mdframed 中的脚注：为什么它们不在页面底部？

Question

当我使用mdframed围绕表格的环境时，遇到了两个问题：（1）脚注没有出现在页面底部；（2）脚注用字母标记，而我的文档中其余的脚注都是阿拉伯语。

我尝试使用该tablefootnote包，但收效甚微。我写下了\footnotemark{}我想要的脚注位置，然后将其放在footnotetext[1]{Text I want}mdframed 环境之外。但这似乎是一个非常糟糕的主意，因为如果我在文档中较早的地方添加脚注，我需要手动调整脚注编号。（例如：如果我添加的脚注早于此，我需要返回并更改为footnotetext[1]{Text I want}。footnotetext[2]{Text I want}）

我附上了一张截图：

生成屏幕截图的代码如下：

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{tabularx}
\usepackage{float}
\usepackage{framed}
\usepackage{tcolorbox}
\usepackage{enumitem}
\usepackage{tablefootnote} %allows footnotes in tables to appear outside the table
%%table packages
\usepackage{booktabs}
\usepackage{threeparttable}
\usepackage{mdframed}

\begin{document}
If I have footnote in the text\footnote{The first footnote} it gets put at the bottom of the page. But if my footnote is inside the \fbox{mdframed} environment, then the footnotes don't appear.

\begin{mdframed}
\begin{table}[H]
\hspace{-5mm}
\begin{tabular}{p{35mm}  p{25mm} <\raggedright }
\underline{Column 1} & \underline{Column 2} \\
Text & more text \\
Text with footnote\footnote{I want this footnote to be at the bottom, and in Arabic numbering!} & ?? \\
\end{tabular}
\end{table}
\end{mdframed}

This should be footnote number three\footnote{The third footnote}, but it is footnote number two.

\end{document}

Answer 1

你可以这样做：

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{tabularx}
\usepackage{float}
\usepackage{framed}
\usepackage{tcolorbox}
\usepackage{enumitem}
\usepackage{tablefootnote} %allows footnotes in tables to appear outside the table
%%table packages
\usepackage{booktabs}
\usepackage{threeparttable}
\usepackage{mdframed}

\begin{document}
If I have footnote in the text\footnote{The first footnote} it gets put at the bottom of the page. But if my footnote is inside the \fbox{mdframed} environment, then the footnotes don't appear.

\begin{mdframed}
\begin{table}[H]
\hspace{-5mm}
\begin{tabular}{p{35mm}  p{25mm} <\raggedright }
\underline{Column 1} & \underline{Column 2} \\
Text & more text \\
Text with footnote\footnotemark{} & ?? \\
\end{tabular}
\end{table}
\end{mdframed}\footnotetext{I want this footnote to be at the bottom, and in Arabic numbering!}

This should be footnote number three\footnote{The third footnote}, but it is footnote number two.

\end{document}

编辑：对原始马可进行了某种形式的修改。已定义两个新马可\myfootnotemark，其功能与原始马可类似。但是，使用时会更新脚注计数器。为了使正文中的上标脚注编号正确输入，已定义一些临时计数器。\myfootnotetext\myfootnotetext

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{tabularx}
\usepackage{float}
\usepackage{framed}
\usepackage{tcolorbox}
\usepackage{enumitem}
\usepackage{tablefootnote} %allows footnotes in tables to appear outside the table
%%table packages
\usepackage{booktabs}
\usepackage{threeparttable}
\usepackage{mdframed}
\newcounter{myfn}
\newcounter{tpmyfn}
\makeatletter
\def\myfootnotemark{%
   \@ifnextchar[\@xfootnotemark
     {\stepcounter{myfn}%
      \setcounter{tpmyfn}{\value{footnote}+\value{myfn}}%
      \protected@xdef\@thefnmark{\thetpmyfn}%
      \@footnotemark}}
      
\def\myfootnotetext{%
     \@ifnextchar [\@xfootnotenext
       {\stepcounter{footnote}\setcounter{myfn}{0}\protected@xdef\@thefnmark{\thempfn}%
    \@footnotetext}}
\makeatother

\begin{document}
If I have footnote in the text\footnote{The first footnote} it gets put at the bottom of the page. But if my footnote is inside the \fbox{mdframed} environment, then the footnotes don't appear.

\begin{mdframed}
\begin{table}[H]
\hspace{-5mm}
\begin{tabular}{p{35mm}  p{25mm} <\raggedright }
\underline{Column 1} & \underline{Column 2} \\
Text & more text \\
Text with footnote\myfootnotemark & some text \\
Text with footnote\myfootnotemark & some text \\
\end{tabular}
\end{table}
\end{mdframed}\myfootnotetext{one}\myfootnotetext{two}

This should be footnote number three\footnote{The third footnote}, but it is footnote number two.

\end{document}

Answer 2

好的，我想我找到了一种方法来做到这一点。它基于@Bernard 的回答邮政。它适用于framed，但如果我尝试仅包含代码，就会发生奇怪的事情\usepackage{mdframed}！如果我将其包含在序言中（不更改任何其他内容），当编译器到达表中的第一个脚注时，我会收到错误。奇怪！

代码：

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{tabularx}
\usepackage{float}
\usepackage{framed}
\usepackage{footnote}
\usepackage{etoolbox}

\BeforeBeginEnvironment{framed}{\savenotes}
\AfterEndEnvironment{framed}{\spewnotes}



\begin{document}
If I have a footnote in the text\footnote{The first footnote} it gets put at the bottom of the page. But if my footnote is inside the \fbox{framed} environment, then the footnotes don't appear.

\begin{framed}
\begin{table}[H]
\hspace{-5mm}
\begin{tabular}{p{35mm}  p{25mm} <\raggedright }
\underline{Column 1} & \underline{Column 2} \\
Text & more text \\
Text with footnote two\footnote{footnote 2} & ?? \\
Text with footnote three\footnote{footnote 3} & more text\\
\end{tabular}
\end{table}
\end{framed}

Now to test with footnotes outside of the `framed` environment: footnote number four\footnote{footnote 4}.
