我正在编写一份“报告”，其中包含几个作业的解决方案，这些作业分为“主题”和“部分”。
我对仅使用部分（标题等于主题名称）得到的结果非常满意，我用重新定义了子部分命令\renewcommand{\thesubsection}{Part \arabic{subsection}}。这很好用。
但现在我想将两部分的答案合并为一个。是否可以将一个小节作为“第 2 和 3 部分“？
\documentclass[11pt,a4paper]{article}
\renewcommand{\thesubsection}{Part \arabic{subsection}}
\begin{document}
\section{Polytropes}
The code used for the computations in this section can be seen in Appendix 1.
\subsection{}
\textbf{ASSIGNMENT}\\
my solution.
\subsection{and 3} %this obviously horrible due to spacing, referencing, counter, etc.
\textbf{ASSIGNMENT of part 2 and 3}\\
my solution.
\end{document}
答案1
我会避免重载\subsection并在此基础上定义适当的命令。在代码中，我没有使用编号部分，而是使用\subsection*并传递预期的标题设置\@currentlabel，它负责正确的交叉引用。
\documentclass[11pt,a4paper]{article}
\makeatletter
\newcommand{\documentpart}{%
\stepcounter{subsection}%
\def\@currentlabel{Part \arabic{subsection}}%
\subsection*{\@currentlabel}%
\addcontentsline{toc}{subsection}{\@currentlabel}%
}
\newcommand{\extradocumentpart}{%
\stepcounter{subsection}%
\def\@currentlabel{Part \@arabic{\c@subsection} and \@arabic{\numexpr\c@subsection+1\relax}}%
\subsection*{\@currentlabel}
\addcontentsline{toc}{subsection}{\@currentlabel}%
\stepcounter{subsection}%
}
\makeatother
\begin{document}
\tableofcontents
\section{Polytropes}
The code used for the computations in this section can be seen in Appendix~1.
\documentpart\label{test1}
\textbf{ASSIGNMENT of \ref{test1}}\\
my solution.
\extradocumentpart\label{test2}
\textbf{ASSIGNMENT of \ref{test2}}\\
my solution.
\documentpart\label{test3}
\textbf{ASSIGNMENT of \ref{test3}}\\
my solution.
\end{document}
如果你也想要实际的标题
\documentclass[11pt,a4paper]{article}
\makeatletter
\newcommand{\documentpart}[1]{%
\stepcounter{subsection}%
\def\@currentlabel{Part \arabic{subsection}}%
\subsection*{\@currentlabel\quad#1}%
\addcontentsline{toc}{subsection}{\@currentlabel\quad#1}%
}
\newcommand{\extradocumentpart}[1]{%
\stepcounter{subsection}%
\def\@currentlabel{Part \@arabic{\c@subsection} and \@arabic{\numexpr\c@subsection+1\relax}}%
\subsection*{\@currentlabel\quad#1}
\addcontentsline{toc}{subsection}{\@currentlabel\quad#1}%
\stepcounter{subsection}%
}
\makeatother
\begin{document}
\tableofcontents
\section{Polytropes}
The code used for the computations in this section can be seen in Appendix~1.
\documentpart{Some title}\label{test1}
\textbf{ASSIGNMENT of \ref{test1}}\\

\extradocumentpart{Some title}\label{test2}
\textbf{ASSIGNMENT of \ref{test2}}\\
