JXL合并SHEET页！
比如现在有3个XLS， a.xls,b.xls,c.xls 每个XLS里面都只有1个SHEET页，sheeta,sheetb,sheetc

请问如何把这3个sheet页，合并到d.xls中不同的sheet页。结果就是d.xls中有3个sheet页。分别是sheeta,sheetb,sheetc.

高分请教，在线等答案。。。

------解决方案--------------------
a.xls.b.xls.c.xls都是有格式的？什么意思？是不是说每个sheet里的字段都不一样？
那也没问题，用三个的不同的类分别封装三个sheet啊！

至于有没有copy或clone的方法...不太清楚哦！
