*在表格中，Rmarkdown中显示错误

我正在尝试使用Rmarkdown创建一个LaTeX表。该表在LaTeX中似乎运行良好，但当我在Rmarkdown上设置它时，它抛出了以下错误：

processing file: table_5.Rmd
output file: table_5.knit.md

! File ended while scanning use of \@argdef.
<inserted text> 
\par 
<*> table_5.tex

---

问题是rmarkdown不够聪明，无法正确解析自定义命令中的

。通过将定义隐藏在.tex文件中并输入此文件，可以避免此问题：
