是否支持单模版多表格填充

填充用的模版文件有了，使用{}设置了一些变量，但是需要在同一个Excel文件中写入多个表格(数量根据业务查询而定)，每个表格变量内容不同而已。是否支持这种场景呢，支持的话API如何调用？

Start by reviewing the repository’s existing template-filling API and documentation for how variables and tables are handled. Determine whether one template can represent multiple tables with runtime-dependent counts and distinct data, then define the API behavior needed for that scenario and document or validate the result.
