nested grid required for column

[magfi.1234]

We are using ParamQuery Pro version 3.1 for our applications. For one of the requirement, we need nested grid for one column. We tried using nested grid but not able to succeed.
Attached is the snapshot for the requirement where for the first row, require multiple entries in the column 3rd (Product).

your requirement look more suitable for row grouping or a tree grid rather than nested grid.
