rs2xml不显示列名和表中的第一行

Question

我有一个返回以下内容的查询

select tyear,sum(total) as total,sum(expected) as expected 
from 
(
select extract(year from date) as tyear ,sum(paid) as total ,sum(amount) as expected 
from term1 group by tyear 
union all 
select extract(year from date) as tyear ,sum(paid) as total ,sum(amount) as expected 
from term2 
group by tyear 
union all 
select extract(year from date) as tyear ,sum(paid) as total ,sum(amount) as expected 
from term3 
group by tyear 
)a group by tyear

从MySQL命令行或工作台我得到这些结果

tyear    total       expected
2012     30000       900000
2013     40000       50000
2014     320000      50000
2015     100000      200000

在我的java代码中，我使用rs2xml.jar来显示上面的表格。问题是，它没有显示第一行，也没有显示列名。

下面的代码行显示表格结果

table3.setModel(DbUtils.resultSetToTableModel(rs));

这是我在java中的内容

2013    11000   13000
2014    772565  66071989
2015    65000   87000
