Question

我怎样才能做出ToC如下的样子？

梅威瑟：

‎\documentclass[10pt,a4paper,openany]{book}‎‎
‎\usepackage{titletoc,xcolor}‎
‎‎
\titlecontents{chapter}% <section-type>
[0pt]% <left>
{}% <above-code>
{\fcolorbox{blue}{blue}{\color{white}\bfseries\chaptername~ \thecontentslabel}}% <numbered-entry-format>
{}% <numberless-entry-format>
{\bfseries\hfill\contentspage}% <filler-page-format>

\begin{document}‎
‎\tableofcontents‎‎
‎
‎\chapter{First Chapter}‎
‎\section{First Section}‎‎‎
‎\section{Second Section}‎‎
‎
‎\chapter{Second Chapter}‎
‎\section{First Section}‎‎
‎\section{Second Section}‎‎
sample
\end{document}‎

Answer 1

第一个试用版，需要对章节标题行进行更多设置。（我使用了传统\addcontentsline方式，而不是titlesec）

章节行不要太长！我只添加了一行来显示这样做的负面影响。

\documentclass[10pt,a4paper,openany]{book}
\usepackage{tocloft}

\usepackage[x11names,dvipsnames,svgnames]{xcolor}

\usepackage[most]{tcolorbox}


\newtcbox{\chapternumberbox}[1][]{%
  colback=blue!50!black,
  colupper={white},
  fontupper={\bfseries\large},
  valign=center,
  size=small,
  nobeforeafter,
  equal height group=chaptertoc,
  #1,
}




\newtcolorbox{chapternamebox}[1][]{%
  enhanced jigsaw,
  valign=center,
  interior style={left color={white!30!blue},right color={white!90!blue}},
  colframe={gray},
  boxrule={1pt},
  colupper={black},
  size=small,
  fontupper={\bfseries\large},
  nobeforeafter,
  equal height group=chaptertoc,
  #1,
}

% A wrapper command
\newcommand{\mychapternamebox}[3][]{%
  \begin{chapternamebox}[#1]
    #2\hfill#3%
  \end{chapternamebox}%
}


\usepackage{xpatch}

\makeatletter
\xpatchcmd{\@chapter}{%
  \addcontentsline{toc}{chapter}%
  {\protect\numberline{\thechapter}#1}%
}{%
  \addtocontents{toc}{\protect\cftpagenumbersoff{chapter}}
  \addcontentsline{toc}{chapter}{\protect\chapternumberbox{\protect\chaptername{} \thechapter}\protect\mychapternamebox[width={9.8cm}]{#1}{\thepage}}%%
  \addtocontents{toc}{\protect\cftpagenumberson{chapter}}%
}{}{}
\makeatother

\begin{document}
\tableofcontents

\chapter{First Chapter}
\section{First Section}‎‎
\section{Second Section}
\chapter{Second Chapter}
\section{First Section}
\section{Second Section}
\chapter{Third Chapter with an excessively long title that should be avoided!}‎‎
