Markdown syntax not working within \multicol environment
问题
为了在两栏中扩展脚注，<https://tex.stackexchange.com/questions/462347/how-to-force-a-footnote-to-extend-over-both-columns-in-a-twocolumn-article?noredirect=1&lq=1> 建议使用\usepackage{multicol}，而不是twocolumn文档选项。
尽管这适用于纯 LaTeX 文档，但当在 multicol 环境中使用 Markdown 格式的元素生成 PDF 输出时，如以下示例所示，对于 RMarkdown 和 pandoc 来说并不适用：
---
title: Sample Document
header-includes: \usepackage{multicol}
output: pdf_document
---
\begin{multicols}{2}
# 第一部分
\end{multicols}
在使用 RMarkdown 时，有什么可能实现脚注跨两栏的方法呢？

For extending footnotes over two columns, <https://tex.stackexchange.com/questions/462347/how-to-force-a-footnote-to-extend-over-both-columns-in-a-twocolumn-article?noredirect=1&lq=1> recommends \usepackage{multicol} instead of the twocolumn document option.
Although this works for pure LaTeX documents, it will not work for generating PDF output by RMarkdown and pandoc when having Markdown-formatted elements within the multicol environment as in:
---
title: Sample Document
header-includes: \usepackage{multicol}
output: pdf_document
---
\begin{multicols}{2}
# First section
\end{multicols}
What could be a possibility to achieve footnotes extending over two columns when using RMarkdown?

Surround the \begin and \end commands with blank lines. If that doesn't work, then mark them as LaTeX snippets like so:
```{=latex}
\begin{multicols}{2}
```
# First section
```{=latex}
\end{multicols}
```
