暫時修改章節標題的版面

我想修改文件中一些「特殊」章節的佈局，但之後重置為我之前使用的佈局，即

\documentclass{report}
\usepackage{titlesec}

\begin{document}

\chapter{Normal Chapter}
\section{Normal Section}
\subsection{Normal Subsection}

% ask for current lay out:

\titlespacing*{\chapter}{0pt}{-40pt}{10pt}
\titleformat{\chapter}{\centering\Large\bf}{}{0pt}{}{}
\titleformat{\section}{\large\bf}{}{0pt}{}
\titleformat{\subsection}{\normalsize\it}{}{0pt}{}

\chapter{Special Chapter}
\section{Special Section}
\subsection{Special Subsection}

% reset to initial lay out

\chapter{Normal Chapter Again}
\section{Normal Section Again}
\subsection{Normal Subsection Again}

\end{document}

如何定義儲存目前設定並隨後使用它們進行重置的變數？

答案1

您可以分組限制範圍：

\documentclass{report}
\usepackage{titlesec}

\begin{document}

\chapter{Normal Chapter}
\section{Normal Section}
\subsection{Normal Subsection}

% ask for current lay out:

\begingroup
\titlespacing*{\chapter}{0pt}{-40pt}{10pt}
\titleformat{\chapter}{\centering\Large\bf}{}{0pt}{}{}
\titleformat{\section}{\large\bf}{}{0pt}{}
\titleformat{\subsection}{\normalsize\it}{}{0pt}{}

\chapter{Special Chapter}
\section{Special Section}
\subsection{Special Subsection}
\endgroup
% reset to initial lay out

\chapter{Normal Chapter Again}
\section{Normal Section Again}
\subsection{Normal Subsection Again}

\end{document}

您也可以定義一個新命令來儲存新設置，然後像以前一樣在群組內使用此命令：

\documentclass{report}
\usepackage{titlesec}

\newcommand\speciallayout{
  \titlespacing*{\chapter}{0pt}{-40pt}{10pt}
  \titleformat{\chapter}{\centering\Large\bf}{}{0pt}{}{}
  \titleformat{\section}{\large\bf}{}{0pt}{}
  \titleformat{\subsection}{\normalsize\it}{}{0pt}{}
}

\begin{document}

\chapter{Normal Chapter}
\section{Normal Section}
\subsection{Normal Subsection}

% ask for current lay out:

\begingroup
\speciallayout
\chapter{Special Chapter}
\section{Special Section}
\subsection{Special Subsection}
\endgroup
% reset to initial lay out

\chapter{Normal Chapter Again}
\section{Normal Section Again}
\subsection{Normal Subsection Again}

\end{document}

為標準佈局定義類似的命令，您現在可以使用這兩個命令切換樣式，而無需明確分組：

\documentclass{report}
\usepackage{titlesec}

\newcommand\speciallayout{
  \titlespacing*{\chapter}{0pt}{-40pt}{10pt}
  \titleformat{\chapter}{\centering\Large\bf}{}{0pt}{}{}
  \titleformat{\section}{\large\bf}{}{0pt}{}
  \titleformat{\subsection}{\normalsize\it}{}{0pt}{}
}
\newcommand\normallayout{
\titlespacing*{\chapter}{0pt}{50pt}{40pt}
\titleformat{\chapter}[display]
  {\normalfont\huge\bfseries}{\chaptertitlename\ \thechapter}{20pt}{\Huge}
\titleformat{\section}
  {\normalfont\Large\bfseries}{\thesection}{1em}{}
\titleformat{\subsection}
  {\normalfont\large\bfseries}{\thesubsection}{1em}{}
}

\begin{document}

\chapter{Normal Chapter}
\section{Normal Section}
\subsection{Normal Subsection}

\speciallayout
\chapter{Special Chapter}
\section{Special Section}
\subsection{Special Subsection}

\normallayout
\chapter{Normal Chapter Again}
\section{Normal Section Again}
\subsection{Normal Subsection Again}

\end{document}
