在excel表中增加杂项报支费用、工程备件领料费用两行数据，要求按月份分别展示

SQL语句为：

select substr(a.paydate,1,6) as paydate,sum(a.materialamt) as amt from
(select * from db.tbcimt3 where APPID=‘INJJ47‘  AND  CIMP1NO=‘18SJ6203‘ and PAYKIND=‘F‘ ) a
group by substr(a.paydate,1,6)
order by substr(a.paydate,1,6)

这条SQL查询出来的数据用map数组接收，在func中对map数组遍历取出对应的月份信息和费用信息，add到list中，数组有多大，就创建几个list，将每个list依次add到dataList中，最后将dataList中的数据打印到excel中，代码如下：

Map map = new HashMap();
map.put("compid", dsCom.companyId);
map.put("cimp1no", cimp1.getCimp1no());
map.put("cimp1name", cimp1.getProjectname());
map.put("sdate", cimp1.getEstimatestartdate());
map.put("edate", cimp1.getEstimatefinishdate());
dxjiTemplateMerger merger = dxjcMergerFactory.buildTemplateMerger();
merger.setMergingDataMap(map);
File rpt = merger.mergeSimpleList("cia", "ciacw6.xls", dataList);
