hi sachin ,
I have been able to add the combobox,
but it is not working, i mean i can see the first element, but when i expannd the combo i dont see any data of the combo, and after collapsing the combo it gets back to the same, state showing the first element.
let me tell you what i have done,
I created the combobox insside the method getTableCellRendererComponent,
and returned it.
is it right, i guess i will have to modify the getvalueat and setvalueta methods also, but i have no clue as to how shoud i modify the same, for using combobox.
