MobX combined with ES6 Class function is a business implementation problem!

Business scenario:
two lists, each using a child store , and then inheriting a common parent store . There are some common methods, such as operation paging, in parent store . The
data structure is designed based on a list. Now how to implement the data structure of the two children store is still inherited, and the data values are different?
