Child table level of DataTable

While doing work involving DataTable, I noticed that when I used another DataTable as a child of a child of the parent DataTable, Nop only generates one set of JS code to get the child from the parent only.  For example, the layout will look like this:
Table 1
      | - Table 2
                | - Table 4
      | - Table 3
                | - Table 5
So far table 1, 2, and 3 are working. If I try to display 4 or 5, it will throw JS error due to one getchild_table_name method in the script.

So does Nop currently support one parent and one child table in DataTable and any plan or suggestion on how to get this scenario to working?

We'll check it. Here is a  work item

Done. Please see this commit

Could you please let me know how to implement this ( adding child-table to another child-table), as I am still facing this issue?

Thank you
