我正在用java swing开发一个应用程序，我的问题是：如果我添加一个新行，GetTableCellRenderComponent没有被调用，我的代码：
表的创建：

public Tablecase() {

       SystemeBaseConnaissance = new LESSymptomesEnsembleEt();
       SystemeBaseConnaissance.lesSymptomesEnsembleEt.add("x");
       initComponents();
       jTable1.setTableHeader(null);
       jTable1.getColumn("Title 1").setCellRenderer(new brmcellrender());

       Model model = new Model();

       jTable1.setModel( model);
       model.addRow(new Object[]{"ss"});
       System.out.println(SystemeBaseConnaissance.lesSymptomesEnsembleEt.size());
    }

我的defaulttablemodel：

class Model extends DefaultTableModel{

    public Model(){

        super();
     this.addRow(new Object[]{"sx"}  );    
       repaint();

    }

    @Override
    public void addRow(Object[] rowData) {
        super.addRow(rowData); //To change body of generated methods, choose Tools | Templates.
    }

}

我的defaultcelleditor：

public class brmcelleditor extends DefaultCellEditor{

    public brmcelleditor(JTextField textField) {
        super(textField);
    }
    }

     public class brmcellrender extends DefaultTableCellRenderer{

    public brmcellrender() {
        super();
        System.out.println("mefgoudabrahim20.Tablecase.brmcellrender.<init>()");
    /**/
    }

    /*affichge */

        @Override
        public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
            System.out.println("mefgoudabrahim20.Tablecase.brmcellrender.<init>qsdqsdqsd()");
            CaseOfTable cas = new CaseOfTable() ; 
            return  ( cas) ;
        }

    }
