typora 标题自动加编号
目录网上看了挺多其他复制粘贴的方法，但是缺点都是第一级 h1 ,都算进去了
按照规范的 markdown 规范，一个 md 文件中只能出现一个 h1,就是标题
所以最大的编号应该就是 h2,所以我拿来改了一下
新建样式
在 Typora\themes 目录下,新建一个base.user.css文件
导入我修改好的 css
已经集成了 标题自动编号, TOC 目录自动编号, 左侧导航栏自动编号
编号默认从 h2 开始计算

enjoy
然后开始使用
需要注意的是，只有导出 html 的时候才能看得见这个样式，如果是直接复制是无法复制走这个序号的，如果想要复制的时候也有需要请自己写 python 脚本，或者有时间我可能会写一个
