Java:为什么JTable不使用TableCellEditor?

我不希望下面的代码在第一次传递中起作用,但我确实希望在getTableCellEditorComponent和getCellEditorValue中遇到调试断点。 为什么在使用jTable时不调用getTableCellEditorComponent或getCellEditorValue?

public class MyTable extends javax.swing.JFrame implements TableModelListener {
    private static final MyTableCellEditor tableCellEditor =
        new MyTableCellEditor();
        ...
    public MyTable() {
        initComponents();
        jTable.getModel().addTableModelListener(MyTable.this);
        ...
    private void initComponents() { // Generated by the Form Editor.
        jTable = new javax.swing.JTable();
        jTable.setCellEditor(tableCellEditor);
        ...
public class MyTableCellEditor extends AbstractCellEditor implements
        TableCellEditor {
    JComponent component = new JTextField();
    public Component getTableCellEditorComponent(JTable table, Object value,
            boolean isSelected, int rowIndex, int vColIndex) {
        if (isSelected) {
            ((JTextField)component).selectAll();
        }
        ((JTextField)component).setText((String)value);
        return component;
    }
    public Object getCellEditorValue() {
        return ((JTextField)component).getText();
    }
}
