我希望我可以为该页面设置不同的列分隔符（如果它是章节的标题页）。到目前为止，我尝试使用条件语句，ifchapterpage其中的代码makeatother位于这里（作者：@Skillmon）但它无法识别我设置的条件，因此没有任何变化。我如何更改仅包含章节标题的页面的 columnsep？我正在用 编译它LuaLaTeX。

\usepackage{geometry}
\geometry{
paper = a5paper,
layout = a5paper,
layoutsize = {148 mm, 210 mm},
includehead = true,
includefoot = true,
inner = 1.5 cm,
outer = 1 cm,
top = 1.5 cm,
bottom = 1.5 cm,
columnsep = .8cm,
}

答案1
你在开始时告诉 TeX，如果这不是章节页面，它应该@outputdblcol以一种方式修补命令，否则以另一种方式修补。然而，在序言中，这不是章节页面。你需要让 TeX 检查每一页。为此，我进入了\ifchapterpageTi钾Z 图片。另外，您永远不会将条件设置为 false。我也添加了此重置。最后，制作tikzpicture不占用空间的更合适的方法是添加overlay。

这是使用 tikzpagenodes 和 everypage 的版本。请注意，\@outputdblcolparacol 或 multicol 不使用。我创建\mycolumnsep它是为了在将其添加到每个页面之前对其进行测试。
不要忘记运行两次，因为[remember picture]。
顺便说一句，您也可以使用此方法来替换 fancyhdr。
