Add combo box to table at row 1.

Add JCombobox into JTable

Answer 1

The combobox in the table is the table's editor component. Unless you want to customize the editor, you do not need to get the item of the combo box (the JTable framework will handle the editing for you). Instead, query the table's model for the values you need. Use JTable.getModel() to retrieve the table's model and use the model's getValue(int, int) method to retrieve the actual values.
