如何在 rmarkdown 中为 PDF 报告添加颜色？

Question

如何在使用 rmarkdown 创建 PDF 报告时为文本的特定部分添加背景颜色。如下所示

我尝试过这样的事情，但它在乳胶中工作，但在 rmarkdown 中没有

\titleformat{\section}{\sffamily\Large\bfseries\rlap{\color{DarkGreen!90}\rule[-0.5ex]{\linewidth}{3ex}\vspace{-3ex}}\sffamily\Large\color{white}}{\thesection}{1em}{}

this is how it looks in latex

this is in rmarkdown

---
title: "Untitled"
output: pdf_document
header-includes:
- \usepackage{amsfonts,amssymb,amsmath}
- \usepackage[table, svgnames]{xcolor}
- \usepackage{titlesec}
- \usepackage{sectsty}
- \usepackage{xcolor, soul}  
- \sectionfont{\color{red}}
- \subsectionfont{\color{green}}
- \subsubsectionfont{\color{blue}}
- \titleformat{\section}{\sffamily\Large\bfseries\rlap{\color{DarkGreen!90}\rule[-0.5ex]{\linewidth}{3ex}\vspace{-3ex}}\sffamily\Large\color{white}}{\thesection}{1em}{}

Answer 1

两个问题：

• rmarkdown 已经加载了 xcolor 而没有注意您需要的选项。作为一种解决方法，您可以通过将必要的选项传递给所有包来欺骗降价

• sectsty 将破坏您通过titlesec 所做的所有更改。不要同时加载它们
