请教各位大佬，如何实现图片中的目录样式？

提问没有给具体信息，所以只在标准文档类 `book` 下做了实现，不保证任何兼容性。实现主要由两部分构成 - 在 `.toc` 文件中，把 `chapter` 以下的条目包在某个环境中。把 `chapter` 的标题保存下来，作为参数传给环境。 - 这个环境用 `tcolorbox` 实现，方便控制样式。 知乎文章《[[LaTeX 尝试] 一种目录样式：章名居左、多个节名居右](https://zhuanlan.zhihu.com/p/176992118)》提供了更详细的介绍和解释。 ```tex \documentclass[openany]{book} \usepackage{xpatch} \usepackage{tikz} \usetikzlibrary{positioning} \usepackage{tcolorbox} \tcbuselibrary{skins, hooks} % actually skins lib loads tikz pkg %TODO % - breakable \makeatletter %\tcbset{ % % similar to def of option `attach boxed title to left top` % attach boxed title to left/.style={ % % used in \tcbset{#1}\node[#3, at={(frame.#2)}] {\tcbox{<title>}}; % attach@title@boxed@top={#1}{left}{west} % }, %} \newtcolorbox{tocchap}[1]{% enhanced, % box beforeafter skip=0pt, width=.6\linewidth, flush right, frame empty, interior empty, overlay={ % left line \draw[line width=2pt, cyan] ([yshift=-15pt]frame.north west) -- ([yshift=15pt]frame.south west); % title % hekip between title and left line is caused by tikz option `node distance` \node[left=of frame, draw] {\tcbtitle}; }, % title detach title, coltitle=cyan, fonttitle=\large, % attach boxed title to left, % boxed title style={ % frame empty, % interior empty % }, % allow manual linebreak in title text title={\parbox{100pt}{\centering #1}}, } \newif\if@first@chapter \@first@chaptertrue % wrap toc entries lower than chapter in `tocchap` env % expected contents of a .toc file: % \contentsline {chapter}{\numberline {1}title}{2}% % \begin {tocchap}{\@currentchapter }% % \contentsline {section}{\numberline {1.1}title}{2}% % \contentsline {section}{\numberline {1.2}title}{2}% % \end {tocchap}% %% default definition of \addcontentsline: %% #1 = one of aux extension, e.g., "toc", "lof", ... %% #2 = toc entry name, e.g., chapter, section, table, ... %% #3 = toc entry title, e.g., \numberline{...}... % \addtocontents{#1}{\protect\contentsline{#2}{#3}{\thepage}% % \protected@file@percent}} \xpretocmd\addcontentsline{% \expandafter\ifx\csname the#2\endcsname\thechapter \if@first@chapter \global\@first@chapterfalse \else \addtocontents{#1}{\protect\end{tocchap}\protected@file@percent}% \fi \fi }{}{\fail} \xapptocmd\addcontentsline{% \expandafter\ifx\csname the#2\endcsname\thechapter \addtocontents{#1}{\protect\begin{tocchap}{\protect\@currentchapter}\protected@file@percent} \fi% }{}{\fail} \AtEndDocument{% \addtocontents{toc}{\protect\end{tocchap}\protected@file@percent}% } % store chapter title in \@currentchapter \renewcommand*\l@chapter[2]{\def\@currentchapter{\let\numberline\@gobble#1}} % reduce left skip of \l@section \renewcommand*\l@section{\@dottedtocline{1}{0em}{2.3em}} \makeatother \begin{document} \tableofcontents \chapter{Title} \section{title} \section{title} \chapter[Long long long \protect\\long title]{Long long long long title} \section{title} \section{title} \section{title} \section{title} \end{document} ``` 

私以为这个样式值 50 元以上，你想白嫖就别想了
