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},

jTable1 = new JTable(model); 
jTable1.getModel().addTableModelListener(new TableModelListener() {

            public void tableChanged(TableModelEvent e) { 
                String str = new String(); 
                String SelectObj = "";                 TableModel model = jTable1.getModel(); 
                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······ 
                        str = str + "" + String.valueOf(i) + ",";

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

          } 
        }); 
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·····
