这是一个java日历。我想在点击日期时添加弹出窗口和编辑视图的功能。 1.如何向JTable的单元格添加动作侦听器？ 2.单击日期（单元格）时存储信息的弹出对话框。

要在JTable单元格中添加动作列表器，您可以这样做。您可以将此Calender_Table变量重命名为calenderTable。
calenderTable.addMouseListener(new MouseAdapter() {
public void mouseClicked(MouseEvent e) {
if (e.getClickCount() == 2) {
JTable target = (JTable)e.getSource();
int row = target.getSelectedRow();
int column = target.getSelectedColumn();
// do some stuff
}
}
});
