在下面的代码中，“部分”页面上有一个目录。但是，文档的第一部分中有很多章节，内容超出了页面的范围。如何将“部分”页面中的目录分成两列，以便所有章节都能正确显示在页面上？
以下是代码：

谢谢。
答案1
这是一个解决方案。multicols来自的环境多色包装内部运行良好\parbox。
代码
\node[anchor=south east] at (\paperwidth-1cm,-\paperheight+1cm){\parbox[t][][t]{8.5cm}{
\printcontents{l}{0}{\setcounter{tocdepth}{1}}%
}};
替换为
\node[anchor=south east] at (\paperwidth-1cm,-\paperheight+1cm){%
\parbox[t][][t]{\textwidth}{%
\columnsep=50pt
\begin{multicols}{2}
\printcontents{l}{0}{\setcounter{tocdepth}{1}}%
\end{multicols}}};
请注意，我们\parbox[t][][t]{8.5cm}用替换\parbox[t][][t]{\textwidth}，并且我们调整了\columnsep=50pt。
