在rmarkDown beamer演示中，在DocumentClass之前包含乳胶包选项

Question

我试图在 rmarkdown中编译以下beamer演示文稿。但是，当它试图渲染rmarkDown文档时，发生错误

! LaTeX Error: Option clash for package xcolor. 

我搜索了Internet，发现我需要在documentclass行之前包括PassOptionsToPackage{table}{xcolor}。将选项应用于已经加载的软件包，也请参见此处

我该如何在rmarkDown中进行？

    - usepackage{threeparttablex}
    - usepackage[normalem]{ulem}  
    - usepackage[table]{xcolor}

    ```{r setup, include=FALSE}
    library(knitr)
    library(kableExtra)
    knitr::opts_chunk$set(echo = FALSE)
    ```
    ```{r positioned_table}
    dt <- mtcars[1:5, 1:6]
    kable(dt) %>%
    kable_styling("striped", full_width = F) %>%
    column_spec(5:7, bold = T) %>%
    row_spec(3:5, bold = T, color = "white", background = "#D7261E")

Answer 1

使用@samcarter的非常有用的评论，我找到了确切的答案。我所需要的是我的rmarkDown文档中的以下yaml标头：

    ---
    title: "My report"
    output: 
      beamer_presentation:
        keep_tex: true
    classoption: xcolor=table
    header-includes:
      - usepackage{booktabs}
      - usepackage{tabu}
      - usepackage{threeparttable}
      - usepackage{threeparttablex}
      - usepackage[normalem]{ulem}
    ---

Answer 2

使用beamer上的 table xcolor选项可以将其传递给文档类。在传统乳胶

中

documentclass[xcolor={table}]{beamer}

对于Markdown https://bookdown.org/yihui/rmarkdown/pdf-document.html#latex-options建议，可以在上面使用

 classoption: xcolor={table}
