保持在Rmarkdown投影仪中无法生成带有以下错误消息的表

Question

我正在尝试在rmarkdown投影仪（Rstudio）中创建下表（如下所示）。它最初可以正常工作，但是自从我更新了R（3.6.3）和Rstudio以来，它一直没有工作。我还更新了所有的pkgs并重新安装了tinytex pkg，但它不断生成以下错误消息：

output file: dp02_slide.knit.md

! File ended while scanning use of \beamer@collect@@body.
<inserted text> 
                \par 
<*> dp02_slide.tex

Error: LaTeX failed to compile dp02_slide.tex. See https://yihui.org/tinytex/r/#debugging for debugging tips. See dp02_slide.log for more info.
