Latex 潘多克“标题格式”标尺

我对YAML数据块有问题。鉴于以下pandoc文件：

---
papersize: a4
geometry: "left=1.5cm,right=1.5cm,top=3cm,bottom=3cm"
fontsize: 12pt
# https://stackoverflow.com/a/43659664/2069099
subparagraph: yes
#documentclass: extarticle
header-includes:
    - \usepackage[explicit]{titlesec}
    - \titleformat{\section}[hang] {\filleft\huge\sc} {label}{20pt}{#1}

---

Hello World
=========== 

Lorem ipsum

我正确地将标题对齐在右边。现在，假设我需要标题下方的全宽标尺，如中所述，需要将\titleformat语句修改为：

papersize: a4
geometry: "left=1.5cm,right=1.5cm,top=3cm,bottom=3cm"
fontsize: 12pt
# https://stackoverflow.com/a/43659664/2069099
subparagraph: yes
#documentclass: extarticle
header-includes:
    - \usepackage[explicit]{titlesec}
    - \titleformat{\section}[hang] {\filleft\huge\sc} {label}{20pt}{#1}[\titlerule\vspace*{4pt}]

---

Hello World
===========    

Lorem ipsum

但这会导致以下错误：

Error producing PDF.
! LaTeX Error: Missing \begin{document}.

Pandoc将该行的一部分解析为标记。因此，当该行以LaTeX形式写入时，将转义特殊字符，以确保is生成与输入相同的文本。这在这里是不需要的，最好的解决方案是将该行显式标记为LaTeX：

标题包括： -\usepack[explicit]{titlesec} -`\titleformat{\section}[hang]{\filleft\mage\sc}{label}{20pt}{1}`{=latex} 也可以标记整个标题，包括：

标题包括：| ```{=乳胶} \usepackage[explicit]{titlesec} \标题格式{\section}[hang]{\filleft\maging\sc}{label}{20pt}{1} ```

---

好的，在YAML区块中通过普通乳胶解决了问题：
