etoc：部分作为单独的多列 mdframed 块

Question

我正在制作一个双栏目录。它非常详细，包含小节、子小节，甚至命名段落。当然，这些栏会覆盖整个页面，并从下一页重新开始。

1) 我希望这些双列块不是从页面边界重新开始，而是从每个新部分重新开始。我接受这些块的高度会有所不同，而且会很不整齐。

2）不再依赖页面边缘提供的自然边界，而是希望两栏区块被 mdframed单独地，必要时跨越页面边界。

etoc.pdf 中提供了下面引用的框架。但它很复杂，而且离我想要的还差得很远，除非有人能帮忙，否则我觉得这会花上我好几个星期的时间。（也欢迎基于 tcolorbox 的解决方案。）

42.5. 命令 \etocframedstyle 、 \etocframed 和 \etoclocalframed

整个目录都带有框架。标题本身没有框架：如果想要框架，应在 \etocframedstyle 或 \etocframed 的 title 参数内设置。背景颜色和边框组件（顶部、左侧、右侧、底部）的颜色通过适当的 \renewcommand 指定（参见第 46.2 节）。由于使用了 minipage，因此生成的目录与分页符不兼容。若要允许分页符，建议在 \etocsettocstyle 的参数中使用 mdframed 39 或 tcolorbox 40 命令。

Answer 1

以下是使用 和 的尝试framed。mdframed我没有尝试tcolorbox。

但我遇到了一个困难：可能是因为multicols便于在它之前或之后分页，所以很难让这些框很好地分页：要么它们不分页，要么它们优先在章节标题之后分页。

所以最后，我注释掉了用法multicols，并在这里发布了单列的示例。

一些评论：

• 因为在两种情况下标题都是以延迟方式打印的（由framed或），所以和必须以某种方式存储然后重新使用，mdframed\etocname\etocnumber

• 因为章节样式可能会关闭一个组，所以\etocglobaldefs在序言中发布一个问题，

• 因为我们重新定义了章节样式，所以etoc会自动为其他级别（章节、子章节、子子章节）使用其自己的自定义线条样式。但是这种自定义样式会删除段落和子段落，并“水平”打印子子章节。因此，完整的示例需要重新设计所有级别。

正如我在 incipit 中解释的那样，它确实适用于multicols可破坏框内的附加环境，只是破坏的位置选择得令人失望，而我对此没有解决方案。因此我没有发布图片。取消注释 MWE 中的相关行以进行测试。

当然，上面的内容需要重新设计以适应 OP 的限制，因为如前所述，使用了自己的 etoc 样式，并且只有章节以自定义方式定义。也许像这样的东西\etocsavedsectiontocline可以有所帮助，因为它们允许重现类默认值。请参阅 etoc 文档。

我正在添加一个版本，该版本在框架章节样式中将章节和子章节设置为类默认值。MWE 已添加\part{TWO}。左侧注释掉的尝试要么在多列中排版整个内容，要么在框架环境中使用多列，每个都有其问题（此处未说明）。

最后，这里是 2 列显示，但使用的是书籍类\twocolumn而不是multicols环境。这似乎工作正常。

诀窍是用来\etocsettocstyle做与目录通常完全相反的事情，即，如果处于单列模式，我们将暂时切换到双列模式。
