Rmarkdown生成PDF时德语表头改英文及标题页与目录分离方法

一、将德语表头改为英文表述 #

PDF出现德语表头（如Inhaltsverzeichnis、Kapitel），是因为未明确设置文档主语言为英文，可通过以下修改解决：

1. 添加英文主语言设置
   在header-includes的polyglossia相关配置中，加入\setmainlanguage{english}，强制将文档主语言切换为英文，表头会自动替换为Table of Contents、Chapter等英文表述。修改后的对应片段如下：

   header-includes:
      - \usepackage{amssymb}
      - \usepackage{amsmath}
      - \usepackage{subfig}
      - \usepackage{algorithm2e}
      - \usepackage{float}
      - \usepackage{booktabs}
      - \usepackage{colortbl}
      - \usepackage[T1]{fontenc}
      - \usepackage{multirow}
      - \usepackage{rotating}
      - \usepackage{textcomp}
      - \usepackage{polyglossia}
      - \setmainlanguage{english}  # 新增：设置主语言为英文
      - \setotherlanguage{greek}
      - \usepackage{mathtools}
   

2. 启用目录显示
   取消output中toc: no的注释，改为toc: true，还可通过toc_depth控制目录显示层级：

   output:
     pdf_document:
       latex_engine: xelatex
       toc: true  # 启用目录
       toc_depth: 3  # 可选：设置目录显示到三级标题
       # 其他配置保持不变
   

二、将标题页与目录页分开 #

要让标题页和目录页各自独立成页，有两种可行方式：

方法1：手动添加LaTeX分页命令 #

在YAML配置块结束后的第一行，添加\newpage命令，强制标题页结束后分页显示目录：

\newpage

方法2：改用bookdown的pdf_book输出格式 #

该格式专为多章节报告设计，会自动处理标题页、目录页的分页逻辑，无需手动添加命令。修改后的output配置如下：

output:
  bookdown::pdf_book:
    latex_engine: xelatex
    toc: true
    toc_depth: 3
    keep_tex: true
    fig_caption: true
    df_print: kable
    extra_dependencies: ["adjustbox", "subfig"]
