[PyQt] How to display multiple data(from 2 different related table) in one cell of QTableWid

[yangjae]

Output:
table 1:
order_ID  date   buyer  ship_chr  total_price
001       01/01  abc    15        240
002       05/01  xyz    10        235

table 2:
order_ID  product    quantity   rate
001       pen        50         2
001       paper      25         1
001       pin        50         2
002       paper      25         1
002       pen        100        2

I want to display in QTableWidget like this:

OrderID  Date   Buyer  Prod   Quantity Rate Shipping Total
001      01/01  abc    pen     50       2    15       240
                       paper   25       1            
                       pin     50       2       
002      05/01  xyz    paper   25       1    10       235
                       pen    100       2
