在章节标题中添加符号

在章节标题中添加符号

我想在章节标题中添加“|”符号或垂直线,使其看起来像这样:

原始代码如下:

\documentclass[svgnames]{book}

\usepackage{tikz}
\usepackage{kpfonts}
\usepackage[explicit]{titlesec}
\newcommand*\chapterlabel{}

\titleformat{\chapter}
  {\gdef\chapterlabel{}
   \normalfont\sffamily\Huge\bfseries\scshape}
  {\gdef\chapterlabel{\thechapter\ }}{0pt}
  {\begin{tikzpicture}[remember picture,overlay]
    \node[yshift=-3cm] at (current page.north west)
      {\begin{tikzpicture}[remember picture, overlay]
        \draw[fill=LightSkyBlue] (0,0) rectangle
          (\paperwidth,3cm);
        \node[anchor=east,xshift=.9\paperwidth,rectangle,
              rounded corners=20pt,inner sep=11pt,
              fill=MidnightBlue]
              {\color{white}\chapterlabel#1};
       \end{tikzpicture}
      };
   \end{tikzpicture}
  }
\titlespacing*{\chapter}{0pt}{50pt}{-60pt}

\begin{document}
\tableofcontents
\chapter{Decision Trees}
Text
\chapter{Main}

\section{Section}
Text
\begin{thebibliography}{99}
\bibitem{Test} test reference

\end{thebibliography}
\end{document}

\chapterlabel #1是插入垂直线的位置。\chapterlabel对于未编号的章节,它为空,或者包含包括尾随空格的章节编号。

可以通过 添加垂直线\vrule。宽度可以通过关键字配置width\vrule width 1pt。高度和深度取决于线的高度和深度,并且可能因章节而异。常量规则可用$|$。粗体版本的后者用于以下示例:

\documentclass[svgnames]{book}

\usepackage{tikz}
\usepackage{kpfonts}
\usepackage[explicit]{titlesec}
\newcommand*\chapterlabel{}

\titleformat{\chapter}
  {\gdef\chapterlabel{}
   \normalfont\sffamily\Huge\bfseries\scshape}
  {\gdef\chapterlabel{\thechapter\ }}{0pt}
  {\begin{tikzpicture}[remember picture,overlay]
    \node[yshift=-3cm] at (current page.north west)
      {\begin{tikzpicture}[remember picture, overlay]
        \draw[fill=LightSkyBlue] (0,0) rectangle
          (\paperwidth,3cm);
        \node[anchor=east,xshift=.9\paperwidth,rectangle,
              rounded corners=20pt,inner sep=11pt,
              fill=MidnightBlue]
              {\color{white}%
                  \ifx\chapterlabel\empty
                  \else
                    \chapterlabel $\boldsymbol{|}$ %
                  \fi
                  #1};
       \end{tikzpicture}
      };
   \end{tikzpicture}
  }
\titlespacing*{\chapter}{0pt}{50pt}{-60pt}

\begin{document}
\tableofcontents
\chapter{Decision Trees}
Text
\chapter{Main}

\section{Section}
Text
\begin{thebibliography}{99}
\bibitem{Test} test reference

\end{thebibliography}
\end{document}
