Hi Prasad,
How about using combined queries? If you care about just showing them in one table.
Create one data provider with 3 combined queries, each combined query should've the same number of objects, Objects with same datatype at each position and eventually, in the report the Object names from the first combined query will be shown. If you still want to show the actual object name from the Combined queries 2 and 3, check this blog, specifically the section "Dummy (label) objects in the universe to use in combined queries"
