谢谢了　

这是我写的一个财务经理考核系统其中生成EXCEL报表的部分，你参考一下吧。最后生成的EXCEL为了免去别人在浏览器中
直接打开而不是提示保存的麻烦我用了smartupload.

呵呵　谢谢了，

不好意思，有一点要补充一下，里面的Border.ALL、BorderLineStyle.THIN、VerticalAlignment.CENTRE、Alignment.CENTRE要指明为：jxl.format.Border.ALL、jxl.format.BorderLineStyle.THIN、jxl.format.VerticalAlignment.CENTRE、jxl.format.Alignment.CENTRE
否则运行时会报引用不明确的错误

恩　，已经在试了　谢谢snowingsky　关心，有问题还是要请教你　．

用水晶报表　能否更好的实现呢
