一个JTable的问题··请指点··谢谢···

Object[][] cells = { {Boolean.FALSE, "必选", "1", ""}, {Boolean.FALSE,
                           "可选",
                           "", ""}, {Boolean.FALSE, "必选", "4", aba},

        String[] columnNames = {"选择", "重要级", "文件名", "说明"};        DefaultTableModel model = new DefaultTableModel(cells, columnNames)
 jTable1 = new JTable(model);
 jTable1.getModel().addTableModelListener(new TableModelListener() {

                int count = model.getRowCount();
                for (int i = 0; i < count; i++) {
                     checked = (Boolean) model.getValueAt(i, 0);
                    //SelectObj=new String();
                    if (checked) {
                        System.out.println(i); //输出选择项······

                            model.setValueAt("1231312",i,1);
                        }
                    }
                }
                //objMyTable.editBol=checked;
                this.isCellEditable(0,1);
                System.out.println(str);
                getAll = SelectObj;
                System.out.println(SelectObj);
            }

        });
我做了一个表格，里面含有Boolean类型的复选框，现在我想创建一个关联，比如说是当某行的第三列为8的时候·，那么在在当选择该行的时候，第八行也在同时被选择上···不知道该怎么实现··
请高手指点··
谢谢·····
