我正在进一步关注以下问题： 在页眉中插入预定义段落编号 我不被允许对这个问题发表评论所以不得不提出一个新问题。
@Andrew。@Sujato 已经离线几个月了，他要求我接手这个问题，因为我有主要文档。
我还有一些问题。其中之一是你在第 6 点上的修改在章节标题和第一节之间创建了一个新的分页符，而之前并没有这个分页符。有什么办法可以解决这个问题吗？
编辑：新的 MWE-希望现在没问题。

正如我们在下面讨论的那样，这个 MWE 中存在两个问题：
- 章节标题现在位于单独的页面上，而不是与章节后面的节标题位于同一页面上。
- 段落编号并不总是正确反映该页面上的数字 - 在第 4 页底部的屏幕截图中，数字为 7-20，而应为 7-18
答案1
以下是代码的修改版本在页眉中插入预定义段落编号。我认为这就是你想要的。
我所设置的是\chapter标志\IsNewChaptertrue，然后命令使用该\section标志来确定是否应该使用开始一个新页面\clearpage。
我认为我在回答上一个问题时测试过这一点，并确定标题中章节编号不正确的问题是由\sectionbreak来自的命令 引起的titlesec 包，但也许我误解了一些事情。
无论如何，这里是完整的代码：
