java，gui，现在弹窗中有一个表格，两个下拉菜单栏。例如，表格第一列记录了学生的性别，第二列为年龄。第一行为“zhang”，28。第二列为“wang”，19。第三列为“zhang”，19，第四列为“wang”，28。则第一个菜单栏为性别，下拉选项有“zhang”，“wang”，第二个菜单栏叫年龄，下拉选项为19，28。通过下拉菜单栏可以实现筛选表格的功能。可以分别筛选，也可以两个菜单栏一起筛选。注释放在外面，不要放在整体代码里

以下是一个简单的Java GUI程序，包含一个表格和两个下拉菜单栏。你可以在菜单栏中选择性别和年龄来筛选表格。

        panel.add(genderComboBox, BorderLayout.CENTER);

        panel.add(ageComboBox, BorderLayout.SOUTH);

    }

    public static void main(String[] args) {
        TableFilterDemo demo = new TableFilterDemo();
    }
