Could this perhaps be your simple standard way?

JComboBox myComboBox = new JComboBox(myAllowableValuesArray);
TableColumn myColumn = myTable.getColumnModel().getColumn(myColumnIndex);
myColumn.setCellEditor(new DefaultCellEditor(myComboBox);


Why does this work? DefaultCellEditor implements the TableCellEditor
interface for you and provides constructors for setting a JTextField, a
JCheckBox or a JComboBox to be the editing component. For other editors
however, you still need to create a subclass that implements the
TableCellEditor interface.
