User defined Objects(Can't map standard grid object in to table object )

[madhavanr]

Since UFT/QTP not supporting my application, I'm using mapping object into standard object(user defined objects) and doing some scripting, now I tried to map standard object(grid) into table object but I didn't see the table option in the list of value in object identification, I know it was in QTP8.2 but after that I didn't use this mapping options, now I'm using UFT11.5 now I checked it, there is no table option in the object identification., screen shot attached for list of values for user defined objects.
Please let me know if anyone know how to define user define object which maps standard grid object into table object.
I have attached the screen shot of list of values in the mapping options.

Thanks
Madhavan
