Knowledge Point Induction:

Extend to merge two lists;

Add ID, edit, delete button to page

1, the List_display inside the field to merge into the new list, and then the edit, delete button and page content display,

Encapsulate these into functions, then pass the Is_header=false, and if true, return the header name;

2. Insert head and form data into table

Doing one thing is traversing, fields and methods
