JProgressBar in JTable

I am trying to use a TableModel to add information into a JTable however I cannot seem to get a ProgressBar imbedded into one of the cells.

Code:

---

public class TestDataModel extends AbstractTableModel {
   
          // By extending AbstractTableModel, instead of
          // implementing TableModel yourself,
          // AbstractTableModel takes care of
          // TableModelListener list management

          String columns[] = {"Name", "Level",
                              "General, "Permit"};
       
          Object rows[][] = {
            {"South", new JProgressBar(), "123 of 200", "1 of 200"},
            {"South", new JProgressBar(), "200 of 200", "200 of 200"},
            {"West", new JProgressBar(), "122 of 200", "123 of 200"},
            {"West", new JProgressBar(), "22 of 200", "1 of 200"},
          };

---

However this code doesn't work is there anything Im missing?
