运行标题有时太长，我尝试使用 \sectionmark，但它不起作用......
梅威瑟：
\documentclass[twocolumn,a4paper,10pt]{book}
\usepackage{fancyhdr}
\pagestyle{fancy}
\usepackage{lipsum}
\begin{document}
\tableofcontents
\section{Introduction}
\lipsum{5}
\section{Here's long text that is two long for the page and I'd like to substitute it but can't figure out how}
\sectionmark[long text]
\lipsum{5}
\end{document}

对于这种情况，类似部分的命令有一个可选参数。
\documentclass[twocolumn,a4paper,10pt]{book}
\usepackage{fancyhdr}
\pagestyle{fancy}
\usepackage{lipsum}
\begin{document}
\tableofcontents
\section{Introduction}
\lipsum{5}
%The next line
\section[This is the shortened version]{Here's long text that is two long for the page and I'd like to substitute it but can't figure out how}
%\sectionmark[long text]
\lipsum{5}
\end{document}
