Is there any option in JTable to add the column number

Question

Hi,
I am using JTable to show some data read from database.
I want to add the column number autometically.(Without by talking a variable and incrementing that by 1.After that add that to the first column.)
I want just like a auto increment row number.
Is there any option in JTable?
Thanks

                    for(int i = 0; i < table.getRowCount(); i++){
                        table.setValueAt(i, i, 0);
                    }
