Latex：创建几个新的子层会导致一些计数错误

Question

我尝试创建一种扩展 Latex 中切片层数的方法。当前的 Layers\section和不够，并且与其他库一起出现问题。因此，我创建了一个可以包含七个层的切片系统，包括\subsection、、、、...... 。代码主要来自\subsubsection\paragraph\subparagraph\section\subsection\twosubsection\threesubsection\foursubsection这个答案。

但是当我在多个二分节中实现三分节时，计数器不会重置（见下面的示例）。此外，附录的章节编号方式错误。第一个子节应该编号为 A.1，而不是 1.1。

你能想到解决这个问题的方法吗？

Answer 1

chngcntr这可以通过使用包和命令轻松完成\counterwithin{threesubsection}{subsubsection}

对于附录中的小节重新编号，您可以包括以下内容

\preto{\appendix}{\renewcommand{\thesubsection}{\Alph{section}. \arabic{subsection}}}
