mdframed 内的 minipage，带有脚注

Question

我需要在mdframed环境中有带标题的表格。由于不能使用浮点数，因此我将captionof与一起使用tabular。当有分页符时（如下面的 MWE 所示），标题和tabular可能会分开。为了防止这种情况发生，我将它们放在里面minipage。但minipage会抓取mdframed脚注。

梅威瑟：

\documentclass{article}
\usepackage{mdframed}
\usepackage{caption}
\usepackage{lipsum}
\newenvironment{ProblemStatement}{
    \mdfsetup{
        innertopmargin=10pt,
        linewidth=0.4pt
    }
    \begin{mdframed}[]
    }
    {
    \end{mdframed}
    \bigskip
}   
\begin{document}
    % text
    \begin{ProblemStatement}
        Blah\footnote{footnote}

        \lipsum[1-4]

        \begin{minipage}{\textwidth}
        \begin{center}
        \captionof{table}{My table}
        \begin{tabular}{|c|c|}
            \hline 
            1& a \\ 
            \hline 
            2& b \\ 
            \hline 
            3& c \\ 
            \hline 
            4& d \\ 
            \hline 
            5& e \\ 
            \hline 
            6& f \\ 
            \hline 
            7& g \\ 
            \hline 
        \end{tabular} 
        \end{center}
        \end{minipage}

        \lipsum[5-6]
    \end{ProblemStatement}
\end{document}

tabular除了使用 之外，还有其他方法让标题和保持在一起minipage吗？ 有没有办法阻止minipage抓取脚注？ 有没有其他方法可以替代mdframed，让浮动可以自由使用？

编辑

可以用xepersian's来做到这一点吗LTRfootnote？

Answer 1

mdframed与 共享脚注内部宏minipage，因此脚注在 内部收集mdframed并由 输出minipage。以下示例利用mdframed其单独的脚注内部，因此避免了该问题。
