Can I get the total number of pages of a template and delete a page?（可以支持获取模板总页数，删除某页的功能么？）

[ByZhouhang]

For example, the template should be internationalized (Chinese and English versions are provided), the template wants to be placed in a file for easy management, before use, use the total page number/2, first kill half, and then import the data into it, so that there is no need to engage in two templates, if it can provide the function of deleting the specified page.

比如模板要做国际化(提供双语版本)，模板想放在一个文件，便于管理，在使用前，利用总页码/2，先干掉一半，再将数据导入进去，这样不用搞两个模板，想要个删除指定页的功能，如果能增加就好了。
