Question

请问一下怎么样在JTable中加入JComBox或JCheckbox
有没有例子

Answer 1

Java本身就自带的JComboBox和JCheckBox的Editor啊你直接设置CellEditor就可以了，DefaultCellEditor支持 JComboBox、JCheckBox的构造new DefaultCellEditor(new JComboBox());new DefaultCellEditor(new JCheckBox());

Answer 2

JComboBox comb;
String[] items = {"请选择","网吧","家里","单位"};
comb = new JComboBox(items);
//comb 绑定到第三列
TableColumnModel tcm = this.getTableHeader().getColumnModel();
TableColumn tc01 = tcm.getColumn(2);
tc01.setCellEditor(new DefaultCellEditor(comb));
this  可以换成你的table名字

Answer 3

买本《java核心技术》吧，上面有详细的例子。有电子版的。

Answer 4

和三楼的基本一个意思String[] cm = {"1111","22222","33333"};
TableColumn tc = table.getColumn(3);
tc.setCellEditor(new DefaultCellEditor(new JComboBox(tc)));

我写的简单例子，请参考一下吧。

最近也在做这个
对JTABLE不太熟悉。
