\part 标题样式

Question

我正在使用\documentclass{book}。我喜欢将我的\part风格重新定义为类似于下图中的东西。所以，我喜欢当我使用部分时，我会得到类似于下图的东西，顶部是“部分”，而不是章节，里面有一个灰色矩形，里面有一个数字。有什么想法可以做到这一点吗？

\documentclass[a4paper]{book}

\usepackage[table]{xcolor}

      \refstepcounter{part}%
      \addcontentsline{toc}{part}{\thepart\hspace{1em}#1}%

Answer 2

另一种解决方案是使用ebgaramond字体及其字母首字母。我试图让代码尽可能通用，但一些参数（主要用于raisebox）可能取决于字体。我还试图让结果尽可能接近 OP 的图片，再加上一些颜色。部分标题的格式是用 进行的titlesec。

添加：我设法epigraphs在部分页面上添加了environ和etoolbox包。要使用的命令是\thispartepigrah{text}{source}。它将布尔值设置withepi为 true，允许将题词显示为 的可选参数\titleformat，然后使用 epi 重置为false。epigraph命令本身是通过虚假环境捕获的PartEpigraph。
