jtable在指定的单元格添加JComboBox

Question

jtable在指定的单元格添加JComboBox
小弟不才，希望大虾们指点一下

Answer 1

想要其中一个为combobox,其他为textfield 
1,我发现用jtable   的   prepareEditor(),   没有效果，   ？？？ 2，于是用方法二继承DefaultCellEditor,覆写getTableCellEditorComponent（），   结果取不到值？？？ 附上部分代码： 
public   class   TestTableCellEditor   extends   DefaultCellEditor   { 
        JComboBox   comboBox   =   new   JComboBox(new   String[]   { "a ",   "b "});         public   TestTableCellEditor   ()   { 
                super(new   JTextField()); 
        }         public   Component   getTableCellEditorComponent(JTable   table, 
                                                                                                  Object   value, 
                                                                                                  boolean   isSelected, 
                                                                                                  int   row, 
                                                                                                  int   column)   { 
                if   (row   ==   0   &&   column   ==   0)   { 
                        comboBox.setSelectedItem(value); 
                        return   comboBox; 
                }   else   { 
                        return   super.getComponent(); 
                } 
        } 
}

lz可以看下这个，利用里面的eachrowrenderer和eachroweditor实例可以做到为一列的不同行添加不同的控件

Answer 4

JComboBox cb = new JComboBox();
            cb.addItem("1");
cb.addItem("2");
            tab.getColumnModel().getColumn(0).setCellEditor(
                    new DefaultCellEditor(cb));

Answer 5

可以参考JDK根目录/demo/jfc/SwingSet2下的SwingSet2.jar中的实例，双击打开后，找到table的实例，，在Source Code标签面板中查看相关源码，其他控件的实例同理（JKD6.0新加了lookandfeel，有时间可研究）
