我试图了解\marks、\firstmarks和如何\botmarks与两列输出一起工作。
在以下 MWE 中，标题按我想要的方式工作，输出一列。右侧标记是第 1 页的最后一节，左侧标记是第 2 页的第一节。
但是当我引入两列（使用包multicols或twocolumn类选项）时，事情就出错了。
第 3 页和第 4 页存在两个问题：
- 第 3 页的标题应为约翰福音 1:12， 不是约翰福音 1:13以匹配页面上的最后一节。（这个错误似乎只发生在
multicols包中，而不是twocolumn类选项中。） - 第 4 页的标题应该是约翰福音 1:13， 不是约翰福音 1:18以匹配页面上的第一节。（此错误在
multicols包和twocolumn类选项中都会发生。）

答案1
multicol 和 twocolumn 多次调用输出例程，这会改变标记。您最好坚持使用标准的 latex 标记命令，因为内核和 multicol 都包含在这种情况下正确重置它们的代码（例如在 multicol 中搜索keptmarks）。
本文档显示了您的标记与标准 \left/\rightmark 之间的区别：
