Fancyhdr 和两列

Fancyhdr 和两列

[twocolumn] 选项和 \fancyhdr 包之间有冲突吗?

页面右侧的页眉显示字母“I”,而不是与该页面上的其他文本一致的页眉。左侧的页眉没有问题。

这是代码,我很抱歉它太长了;它是由 Pandoc 自动生成的。我仔细检查了一遍,但还是搞不清楚是什么导致了错误。

它必须是序言中的内容,我尝试使用仅包含标题部分和 fancyhdr 包的 MWE,并且标题运行正常。

下图显示了有问题的字符“I”(或者是右边的“[”)

我也尝试使用 Koma 类、scrbook 并删除所有“标题”条目保存

\pagestyle{headings}

但结果就是这样。

从序言中删除章节行:

更新:至少在 Koma 类中;所有背面页面上的“0 [”已被“Contents”一词取代。现在我要做的就是更改“Contents”以与页面上的内容相对应。文档最初属于 Article 类,该类没有章节标题,但在书籍类中很容易用“Chapter”替换“Section”。但这会消除页眉中的“Contents”一词吗?

将“section”改为“Chapter”解决了这个问题,或者至少删除了“Contents”这个词并替换为章节的名称。
