value.addActionListener(this);
//动作
public void actionPerformed(ActionEvent e) {
String s=e.getActionCommand();
if(s.equals("取值")){
try{
System.out.println(jt.getSelectedRow()); //获取行值
System.out.println(jt.getSelectedColumn()); //获取列值
System.out.println(jt.getValueAt(jt.getSelectedRow(), jt.getSelectedColumn())); //通过行值和列值 获得里面的value
}
catch(Exception ee){
System.out.println("什么也没选中");
}
}
学习用的代码。。。 关键看 cmd 那里
只需要通过jtable的方法
getValueAt(int row, int column)就可以了。事件该干什么就还让他干什么，用jtable的对象来得到值就ok了
