章节格式中的目录

我正在尝试为每个章节创建一个目录（请参阅下面的 MNWE）。当表格长度超过页面长度并应该中断时，就会出现问题。对于设置，我使用 tcolorbox 库，它具有大量自定义选项。我使用了一个应该breakable可以确保这一点的选项，但不幸的是它没有。见下图。

使用 可将内容插入章节序言中\setchapterpreamble。这非常有用 - 我使用的是双列格式，类选项为 twocolumn，因为标题和序言始终设置为单列布局。序言可能不能超过两页。

如果您对如何使用不同的解决方案实现相同的效果有任何其他想法，我会很高兴听取您的建议。

KOMA-Script 使用可选参数\@topnewpage（内部命令也使用\twocolumn）在双列文档中打印跨章标题和序言的列。LaTeX 内核为此参数使用一个框，因此不支持在此参数内分页。您需要对每一章的内容使用onecolumn模式和包。但据我所知仍然不起作用，因为它还为序言使用了一个显式框。multicol\setchapterpreamble

下面是一个不自动打印章节目录并切换到两栏的示例：

也许您还可以找到钩子来自动添加\printchaptertoc，\begin{multicols}{2}和\end{multicols}。

注意：multicols处理类似figure和table不同的浮点数。有关更多信息，请参阅手册。
