将两个脚注流并排布置

Question

我正在与一位需要两个不同脚注流的作者合作。这可以很容易地通过使用 来实现bigfoot。

---

编辑 还要注意，使用的边距很窄，大约 10 毫米左右。因此，第二条流应该位于文本“下方”。

---

我做过类似的事情：

\documentclass[a5paper,11pt]{scrbook}
\usepackage{geometry}
\usepackage{perpage}
\usepackage[ruled]{bigfoot}
\MakePerPage{footnote}

\renewcommand{\thefootnote}{\alph{footnote}}
\DeclareNewFootnote{A}[arabic]

\begin{document}
Lorem\footnote{a footnote stream} ipsum dolor sit amet, consectetur adipiscing elit.             
Vestibulum ut lorem\footnote{a footnote stream} ligula. Pellentesque eget nibh quam.     
Etiam molestie iaculis dictum. Ut fringilla odio quis quam aliquet egestas. Nam     
dignissim ante eu nibh bibendum, a laoreet ipsum\footnoteA{another footnote stream} 
aliquam. Donec euismod erat ac malesuada sodales. Fusce viverra feugiat ligula vel 
rhoncus. Aliquam erat volutpat. Nullam consequat sollicitudin quam, id dapibus tellus.     
Nulla tempus mattis justo, eget aliquam elit vehicula sed.

Curabitur ante felis, rutrum sed sem nec, fringilla rhoncus metus. Mauris blandit, dui 
non tempus porttitor, sapien urna fermentum ligula, nec molestie dolor lacus vel 
ipsum\footnoteA{another footnote stream}. Maecenas odio enim, vulputate sit amet nulla 
nec, laoreet imperdiet sapien. Cum sociis natoque penatibus et magnis dis parturient 
montes, nascetur ridiculus mus. Integer sed tincidunt dolor. Nunc laoreet interdum 
condimentum. Maecenas neque urna, porttitor ac neque id, gravida cursus odio.

In egestas lobortis nisi eu malesuada. Donec leo nibh, vulputate vel arcu vel, 
adipiscing pharetra ipsum\footnoteA{another footnote stream}. Maecenas vitae augue 
luctus, ultrices nisi sed, hendrerit ipsum\footnoteA{another footnote stream}. 
Suspendisse potenti. Mauris id blandit arcu, et sodales massa. Sed laoreet dapibus 
lectus id bibendum. Nunc eget orci id lectus auctor sagittis. Vivamus tincidunt semper 
mattis. Curabitur quis lorem\footnote{a footnote stream} tortor.

Sed volutpat urna ligula, eget posuere neque condimentum eu. Integer feugiat erat ac 
lorem interdum, ut pharetra quam blandit. Nulla blandit sit amet tellus at cursus. Nam 
eget eleifend felis. Aliquam pulvinar mi sit amet magna gravida congue. Mauris 
pellentesque dui et turpis laoreet dictum. Donec commodo ultricies risus, eget 
fringilla sapien hendrerit eu.
\end{document}

但是作者问我，是否有可能一条流位于另一条流旁边，而不是位于另一条流下方。

当然，如果给定页面中仅存在第二个流，则将其单独放在右侧。

---

有什么方法可以实现这一点？我尝试使用scrextend可帮助我设置脚注左右边距的包，但这似乎无法解决我的问题。

Answer 1

（按要求。）下面是一个示例，说明如何memoir设置具有两个不同脚注流的双列脚注。但是，将它们并排堆叠需要认真的技术人员的工作……

\documentclass{memoir}
\usepackage[T1]{fontenc}
\usepackage{lipsum,ragged2e}% ragged2e provides \RaggedRight

% Two-column footnotes
\twocolumnfootnotes% look at approx. lines 9327-9429 in memoir.cls

% Set up new footnote series
\newfootnoteseries{A}
\twocolumnfootstyle{A}
\renewcommand{\thefootnoteA}{\alph{footnoteA}}

% Styling of (all) footnotes
\renewcommand{\foottextfont}{\footnotesize\RaggedRight}

\begin{document}

\footnote{\lipsum*[1]}%
\footnoteA{This is the `A' Level. \lipsum*[3]}%
\lipsum[1-2]
\footnote{\lipsum[2]}%
\footnoteA{This is the `A' Level.}%
\lipsum[3-4]

\end{document}
