如何引用附录中的项目

Question

我想在附录中列出项目列表，然后在正文中引用这些项目：

\documentclass{article}
\usepackage[hidelinks]{hyperref} 
\usepackage{appendix}
\begin{document}

Citing appendix section (\ref{sec:appendix:A})

Autoref citing appendix section (\autoref{sec:appendix:A})

Citing an item under appendix setcion A (\ref{figure::appendix::1})

Autoref citing an item under appendix setcion A (\autoref{figure::appendix::1})

\appendix
\appendixpage

\section{A section}
\label{sec:appendix:A}

\begin{enumerate}
  \item Item 1 \label{figure::appendix::1}
\end{enumerate}

\end{document}

如您所见，附录 A 中的第一项被引用为 1 或第 1 项，如何使其显示为附录 A.1 或 A.1 之类的内容？

Answer 1

\theenumi进入文档的附录部分后，只需重新定义：

\renewcommand\theenumi{\thesection.\arabic{enumi}}

\documentclass{article}
\usepackage[hidelinks]{hyperref} 
\usepackage{appendix}
\begin{document}

\noindent
\begin{tabular}{@{}ll}
\ref{sec:appendix:A} & Cross-reference an appendix section \\
\autoref{sec:appendix:A} & Autoref-crossreference an appendix section \\
\ref{item:app:b:2} & Cross-reference an item under appendix section B \\
\autoref{item:app:b:2} & Autoref-crossreference an item under appendix section B 
\end{tabular}

\appendix
\appendixpage
\renewcommand\theenumi{\thesection.\arabic{enumi}}

\section{A section}
\label{sec:appendix:A}

\begin{enumerate}
  \item Item 1 \label{figure::appendix::1}
\end{enumerate}

\section{B section}
\label{sec:appendix:B}

\begin{enumerate}
  \item Item 1 
  \item Item 2 \label{item:app:b:2}
\end{enumerate}

\end{document}
