定心部分

Question

我想要使​​用titlesec 以下方式将我的部分居中（MWE）：

\documentclass[10pt,a4paper,twoside]{book}
\usepackage[latin1]{inputenc}
\usepackage{lipsum}
\usepackage{titlesec}
\titleformat{\section}% command to format the section titles
        [block]% shape/type of title
        {\LARGE\bfseries}% formatting commands applied to both label and title
        {\begin{center} \thesection \end{center}}% section number; here set inside an invisible box with a constant width
        {0em}% separation between number and chapter title; we've already covered this with the box
        {}% additional formatting command for title itself not applied to number
        [
        ]%
\begin{document}
\chapter{The first chapter}
\lipsum[1-5]
\section{First section}
\lipsum[3]
\section*{Section}
\lipsum[4]

\end{document}

但是这不会使部分标题居中，而且也不太美观。如何使用 使部分美观地居中titlesec？

Answer 1

如果您按照 cfr 的建议\centering操作，它就会起作用。\LARGE\bfseries

\titleformat{\section}% command to format the section titles
        [block]% shape/type of title
        {\LARGE\bfseries\centering}% formatting commands applied to both label and title
        {\thesection}% section number; here set inside an invisible box with a constant width
        {1ex}% separation between number and chapter title; we've already covered this with the box
        {}% additional formatting command for title itself not applied to number
        [
        ]%

给出

您也可以使用简化格式

\titleformat*{\section}{\LARGE\bfseries\centering}

代替\titleformat。

\documentclass[10pt,a4paper,twoside]{book}
\usepackage[latin1]{inputenc}
\usepackage{lipsum}
\usepackage{titlesec}
%\titleformat{\section}% command to format the section titles
%        [block]% shape/type of title
%        {\LARGE\bfseries\centering}% formatting commands applied to both label and title
%        {\thesection}% section number; here set inside an invisible box with a constant width
%        {1ex}% separation between number and chapter title; we've already covered this with the box
%        {}% additional formatting command for title itself not applied to number
%        [
%        ]%

\titleformat*{\section}{\LARGE\bfseries\centering}
\begin{document}
\chapter{The first chapter}
\lipsum[1-5]
\section{First section}
\lipsum[3]
\section*{Section}
\lipsum[4]

\end{document}

正如 Bernard 提醒的那样，您还可以使用\filcenterprovided bytitlesec来代替\centering。

sectsty但如果可能的话，它会像 AboAmmar 的回答一样易于使用。

Answer 2

sectsty使用包的快速解决方案

\documentclass[10pt,a4paper,twoside]{book}
\usepackage[latin1]{inputenc}
\usepackage{lipsum}
%\usepackage{titlesec}
\usepackage{sectsty}

\allsectionsfont{\centering}

\begin{document}
\chapter{The first chapter}
\lipsum[1-5]
\section{First section}
\lipsum[3]
\section*{Section}
\lipsum[4]

\end{document}

或者，titlesec只需添加[center]选项即可使用，如下所示：

\documentclass[10pt,a4paper,twoside]{book}
\usepackage[latin1]{inputenc}
\usepackage{lipsum}
\usepackage[center]{titlesec}

\begin{document}
\chapter{The first chapter}
\lipsum[1-5]
\section{First section}
\lipsum[3]
\section*{Section}
\lipsum[4]

\end{document}
