我想只包含小節的小節編號,而不包含小節編號。
我認為這個 MWE 總結了我所追求的。有替代方案嗎\ref
?
\documentclass{article}
\begin{document}
\section{Section A}
\section{Section B}
\section{Section C}
\subsection{Subsection 1}
\subsection{Subsection 2}
\label{subsec:Subsection}
I would like "\ref{subsec:Subsection}" to just return "2".
\end{document}
答案1
這是一個基於我從《The LaTeX Companion》(第二版)一書中學到的技術的解決方案。它執行\renewcommand\thesubsection{\arabic{subsection}}
重置計數器的表示subsection
,並使用低級 LaTeX 命令\subsection@cntformat
,該命令控制subsection
計數器在子部分級條目中的顯示方式。
hyperref
此解決方案在設計上與和cleveref
套件及其交叉引用巨集(例如\autoref
、\cref
和 )相容\labelcref
。
附錄 2019/08/08:我在程式碼中新增了兩行,以概括處理subsubsection
層級標頭的解決方案。
\documentclass{article}
\usepackage{geometry} % optional
\renewcommand\thesubsection{\arabic{subsection}}
\renewcommand\thesubsubsection{\arabic{subsubsection}}
% Method proposed in "The LaTeX Companion", 2nd ed.:
\makeatletter
\def\@seccntformat#1{\@ifundefined{#1@cntformat}%
{\csname the#1\endcsname\space}% default
{\csname #1@cntformat\endcsname}}% enable individual control
\def\subsection@cntformat{\thesection.\thesubsection\space}
\def\subsubsection@cntformat{\thesection.\thesubsection.\thesubsubsection\space}
\makeatother
%Optional:
\usepackage[colorlinks,allcolors=blue]{hyperref}
\usepackage[noabbrev,nameinlink]{cleveref}
\crefname{subsection}{subsection}{subsections}
\crefname{subsubsection}{subsubsection}{subsubsections}
\begin{document}
\setlength\parindent{0pt} % just for this example
The instructions \verb+\ref{sec:C2}+ and \verb+\labelcref{sec:C2}+ return ``\ref{sec:C2}'' and ``\labelcref{sec:C2}''.
The instructions \verb+\ref{sec:C11}+ and \verb+\labelcref{sec:C11}+ return ``\ref{sec:C11}'' and ``\labelcref{sec:C11}''.
\verb+\autoref+: \autoref{sec:C2} and \autoref{sec:C11}
And \verb+\cref+: \cref{sec:C2,sec:C11}
\addtocounter{section}{2} % just for this example
\section{Section C}
\subsection{Subsection 1}
\subsubsection{Subsubsection 1} \label{sec:C11}
\subsection{Subsection 2} \label{sec:C2}
\end{document}
