如何均匀增加 manyfoot 脚注内的垂直间距？

Question

在消除由于 setspace 设置而导致的单个脚注（以及显示在页面底部的脚注）内不需要的垂直间距我们明确地将脚注切换回单倍行距，无论全局\setstretch是什么。如果您还想\setstretch应用于脚注，请删除。由于这首先\def\baselinestretch {\setspace@singlespace}%是重新定义的全部目的，您可以\MFL@fnoteplain消除整个街区

\makeatletter
\long\def\MFL@fnoteplain#1#2#3{\NCC@makefnmark{#2}%
  \MFL@insert#1{\def\baselinestretch {\setspace@singlespace}%
    \reset@font\footnotesize
    \interlinepenalty\interfootnotelinepenalty
    \hsize\MFL@columnwidth \@parboxrestore
    \protected@edef\@currentlabel{\@thefnmark}%
    \color@begingroup
      \MFL@applyhook{#1}%
      \@makefntext{%
        \rule\z@\footnotesep\ignorespaces#3\@finalstrut\strutbox}%
    \color@endgroup
  }%
}
\makeatother

重新定义后，\setstretch再次应用于脚注，并扩大行距（因此空间之内脚注被放大）。

空间之间脚注由控制\footnotesep，您可以轻松地将该长度乘以任何因子

\setlength{\footnotesep}{<factor>\footnotesep}

在 MWE 中，我选择了因子 2 来夸大效果，但您当然可以将这两个2s 更改为1.3。

如果你希望脚注中的行间距与正常文本中的行间距不同，你可以恢复重新定义\MFL@fnoteplain并强制使用不同的值\baselinestretch

\makeatletter
\long\def\MFL@fnoteplain#1#2#3{\NCC@makefnmark{#2}%
  \MFL@insert#1{\def\baselinestretch {4}%
    \reset@font\footnotesize
