how to add data arrays in datatables in laravel

I want to create datatables, with the data that I got from the query builder, and I want to add that data to an array that I process myself, I try with this code

 return Datatables::of($users)
                ->addIndexColumn()
                ->addColumn('number_rek', $array)
                ->make(true);  

but the data is like this

balance: "405.868"
no_register: ["4211070802", "5212370803", "-", "-", "-"]
0: "4211070802"
1: "5212370803"
2: "-"
3: "-"
4: "-"
DT_RowIndex: 1

my expectation is that each row of datatables has one no_register like this

balance: "405.868"
no_register: "4211070802"
DT_RowIndex: 1

balance: "502.500"
no_register: "5212370803"
DT_RowIndex: 2

i use library from yajrabox
