自动更新基于其他工作表的数据的表

Question

如果我在一张纸上有这样的数据

@XmlRootElement(name = "parent")
public class Parent {

    @XmlElements({
        @XmlElement(name = "son", type = Son.class),
        @XmlElement(name = "daughter", type = Daughter.class)
    })
    protected List<Object> sonOrDaughter;

    ...
}

并且我想用它在另一个表中生成单独的表，以这样的方式显示该数据

value | key
============
apple |  1
pear  |  1
orange|  2
cat   |  2
dog   |  3

如果我更新了数据（例如cat：2-> cat：3），表格将自动更新
