保留章节和子章节编号，删除子章节

Question

由于印刷偏好，我想使用小节作为我的小节。但是，我不想使用一个带有零的占位符来表示不存在的子节编号。我该如何去掉这些零？

\documentclass{article}
\begin{document}
\section{Section} 
\subsection{Subsection Header Too Big For Me}
\subsubsection{I Want This Numbered as a Subsection}
\section{Other Section} 
\subsubsection{I Don't Want This Zero in the Middle}
\subsubsection{For Example, This Should be ``2.1''}
\section{Third Section} 
\subsubsection{This Should Be Numbered ``3.1''}
\subsubsection{I Don't Want This ``0'' for a Non-Existent Subsection}
\end{document}

Answer 1

如果它只是关于排版和事物的外观，您可以使用以下方法重新定义小节：

\makeatletter    
\renewcommand\subsection{\@startsection {subsection}{1}{\z@}%
                                  {-3.5ex \@plus -1ex \@minus -.2ex}%
                                  {2.3ex \@plus.2ex}%
                                  {\centering\normalfont\large\bfseries}}
\makeatother

只需替代大的满足您的任何需求。

Answer 2

我刚刚在下面添加了这一行，问题就解决了。我可以删除子节编号之间的所有零：

\renewcommand{\thesubsubsection}{\thesection.\arabic{subsubsection}}

Answer 3

如果你这样做，从终端窗口，

latexdef subsection subsubsection`

\subsection你将获得和的标准定义\subsubsection

\subsection:
\long macro:->\@startsection {subsection}{2}{\z@ }{-3.25ex\@plus -1ex \@minus -.2ex}{1.5ex \@plus .2ex}{\normalfont \large \bfseries }

\subsubsection:
\long macro:->\@startsection {subsubsection}{3}{\z@ }{-3.25ex\@plus -1ex \@minus -.2ex}{1.5ex \@plus .2ex}{\normalfont \normalsize \bfseries }

所以你会发现，简单的区别就是字体大小。好吧，你怎么能轻易解决这个问题呢？有两种方法，但都不依赖于使用\subsubsection而不是\subsection。

方法 1：sectsty

\documentclass{article}
\usepackage{sectsty}

\subsectionfont{\normalsize}

\begin{document}
\section{Section} 
\subsection{I Want This Numbered as a Subsection}
\section{Other Section} 
\subsection{I Don't Want This Zero in the Middle}
\subsection{For Example, This Should be ``2.1''}
\section{Third Section} 
\subsection{This Should Be Numbered ``3.1''}
\subsection{I Don't Want This ``0'' for a Non-Existent Subsection}
\end{document}

有两个无害的警告。

方法 2：etoolbox

\documentclass{article}
\usepackage{etoolbox}

\patchcmd{\subsection}{\large}{\normalsize}{}{}

\begin{document}
\section{Section} 
\subsection{I Want This Numbered as a Subsection}
\section{Other Section} 
\subsection{I Don't Want This Zero in the Middle}
\subsection{For Example, This Should be ``2.1''}
\section{Third Section} 
\subsection{This Should Be Numbered ``3.1''}
\subsection{I Don't Want This ``0'' for a Non-Existent Subsection}
\end{document}
