简单粗暴的解决方案基于\fbox

我想要精确的此部分样式，但无法在其周围添加框架。你能帮帮我吗？这是我的代码片段：

\documentclass[10pt,a4paper,twoside]{report}
\usepackage{blindtext}
\usepackage{titlesec, blindtext, color}
\definecolor{seccolor}{RGB}{41,48,57}
\newcommand{\hsp}{\hspace{8pt}}
\titleformat{\section}[hang]{\Large\bfseries}{\thesection\hsp\textcolor{seccolor}{|}\hsp}{0pt}{\Large\bfseries}

\begin{document}
    \section{Section Name}
    \blindtext
\end{document}

你可以和 Ti 一起拥有它钾Z 和explicit选项titlesec：

\documentclass[10pt,a4paper,twoside]{report}
\usepackage{blindtext}
\usepackage[explicit]{titlesec}
\usepackage{color}
\usepackage{tikz}
\definecolor{seccolor}{RGB}{41,48,57}
\newcommand{\hsp}{\hspace{8pt}}
\titleformat{\section}
    [hang]
    {\Large\bfseries}
    {}
    {0pt}
    {\tikz\node[draw]{\Large\bfseries\thesection\hsp\textcolor{seccolor}{|}\hsp#1};}
\begin{document}
\section{Section Name}
\blindtext
\end{document}

对于很长的章节标题（借助这个问题)：

\documentclass[10pt,a4paper,twoside]{report}
\usepackage{blindtext}
\usepackage[explicit]{titlesec}
\usepackage{color}
\usepackage{tikz}
\usepackage{varwidth}
\usepackage{calc}
\tikzset{
    max width/.style={
        execute at begin node={\begin{varwidth}{#1}},
        execute at end node={\end{varwidth}}
    }
}
\definecolor{seccolor}{RGB}{41,48,57}
\newcommand{\hsp}{\hspace{8pt}}
\titleformat{\section}
    [hang]
    {\Large\bfseries}
    {}
    {0pt}
    {\tikz\node[draw,max width=\textwidth-.6666em-.4pt]{\Large\bfseries\thesection\hsp\textcolor{seccolor}{|}\hsp#1};}
\begin{document}
\section{Section Name}
\blindtext
\section{This is a very long section name that has to be broken into two lines}
\end{document}

如果希望用“|”代替“—”，如附图所示，可以使用\textbar：

\documentclass[10pt,a4paper,twoside]{report}
\usepackage{blindtext}
\usepackage[explicit]{titlesec}
\usepackage{color}
\usepackage{tikz}
\usepackage{varwidth}
\usepackage{calc}
\tikzset{
    max width/.style={
        execute at begin node={\begin{varwidth}{#1}},
        execute at end node={\end{varwidth}}
    }
}
\definecolor{seccolor}{RGB}{41,48,57}
\newcommand{\hsp}{\hspace{8pt}}
\titleformat{\section}
    [hang]
    {\Large\bfseries}
    {}
    {0pt}
    {\tikz\node[draw,max width=\textwidth-.6666em-.4pt]{\Large\bfseries\thesection\hsp\textcolor{seccolor}{\textbar}\hsp#1};}
\begin{document}
\section{Section Name}
\blindtext
\end{document}

不过，我认为像这样的垂直线要好得多。

\documentclass[10pt,a4paper,twoside]{report}
\usepackage{blindtext}
\usepackage[explicit]{titlesec}
\usepackage{color}
\usepackage{tikz}
\usepackage{varwidth}
\usepackage{calc}
\usetikzlibrary{positioning}
\tikzset{
    max width/.style={
        execute at begin node={\begin{varwidth}{#1}},
        execute at end node={\end{varwidth}}
    }
}
\definecolor{seccolor}{RGB}{41,48,57}
\newcommand{\hsp}{\hspace{8pt}}
\titleformat{\section}
    [hang]
    {\Large\bfseries}
    {}
    {0pt}
    {\tikz[font=\Large\bfseries]{\node[draw,minimum height=.75cm] (x) {\thesection};\node[minimum height=.75cm,below right=0pt and 0pt of x.north west,draw,max width=\textwidth-.6666em-.4pt]{\hspace{.3333em}\phantom{\thesection}\hspace{.3333em}#1};}}
\begin{document}
\section{Section Name}
\blindtext
\section{This is a very long section name that has to be broken into two lines}
\end{document}

一个简单的解决方案tabulary：

\documentclass[10pt, a4paper,svgnames, twoside]{report}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[showframe]{geometry}
\usepackage{blindtext}
\usepackage{array, tabulary}
\usepackage[explicit]{titlesec}
\usepackage{blindtext, xcolor}
\definecolor{seccolor}{RGB}{41,48,57}
\newcommand{\hsp}{\hspace{8pt}}
\titleformat{\section}[block]{\Large\bfseries\sffamily\setlength{\fboxrule}{1pt}\color{SlateGrey}}{}{0pt}{\fbox{\begin{tabulary}{\dimexpr\linewidth-\tabcolsep-\fboxrule}{@{}l!{\vline width 1.2pt}L}\thesection &#1 \end{tabulary}} }

\begin{document}

\setcounter{chapter}{2}
    \section{Section Title. Some more more text to have a really very very long section title.}
    \blindtext
    \section{A much shorter section title}
\blindtext

这篇文章包含两个解决方案：一个简单的解决方案和一个更复杂的解决方案。

简单粗暴的解决方案基于\fbox

让我们从基于 的简单解决方案开始\fbox，这很容易理解。我们使用\textbar表示垂直条，并为未编号部分提供变体（\section*）：

\documentclass[10pt,a4paper,twoside]{report}
\usepackage{xcolor}
\usepackage[explicit]{titlesec}
\usepackage{blindtext}

\definecolor{seccolor}{RGB}{41,48,57}
\newcommand{\hsp}{\hspace{8pt}}

\newcommand*{\sectionFont}{%
  \Large\bfseries
}

% For \section
\titleformat{\section}[block]{\sectionFont}{}{0pt}{%
  \fbox{\thesection \hsp \textcolor{seccolor}{\textbar}\hsp #1}}

% For \section*
\titleformat{name=\section, numberless}[block]{\sectionFont}{}{0pt}{%
  \fbox{#1}}

\begin{document}
\chapter{Some chapter}

\section{Section title}

Foo bar.

\section*{Unnumbered section}

\blindtext
\end{document}

使用 TikZ 的更精细的解决方案

\fbox如果您想要比(\fboxsep和\fboxrule)允许的更精细的控制，那么使用tikzpicture框架的环境是一个不错的选择。下面是可以这样做的示例。它实现了与以下类似的设计JouleV 的解决方案但尝试进行更清晰的定位，以确保节号的基线始终与节图块第一行的基线对齐。由于我们拥有 TikZ 的所有功能，我们还添加了一些只需几个关键字即可实现的花哨功能：rounded corners，drop shadow以及标题框的背景填充。

（再多一点黑客技术，甚至可以检测到何时章节标题占用多行，并且只有在这种情况下才使用垂直居中来显示章节编号！）
