How to add CompositeCell to the CellTable

I am trying to CompositeCell with three checkboxes and a button

  hasCells.add(new HasCell<Contact, Boolean>()

        {

            private CheckboxCell cell = new CheckboxCell();

            @Override

            public Cell<Boolean> getCell()

            {

                return cell;

            }

            @Override

            public FieldUpdater<Contact, Boolean> getFieldUpdater()

            {

                return null;

            }

            @Override

            public Boolean getValue(Contact object)

            {

                return object.control;

            }

        });
        final CompositeCell<Contact> compositeCells = new CompositeCell<Contact>(hasCells);

But how do we add this cell to the CellTable and how to provide the text for the Checkboxes. I couldnt find any examples of this in gwt samples.
