JXL是Java Excel的缩写,与名字相应,它是一个JAVA读写Excel文件的工具类,当然有另外的一个被称之为JAVA与Excel的完美解决方案POI,不过我没用过,以后再去尝试一下,因为当前做的项目的旧代码中有涉及到JXL的应用,所以就特地了解了一下,感觉就一个字,简单易用,感觉像是在用GWT的FlexTable,行列有个坐标,把相应的东西放到相应的坐标就行了,当然还有合并单元格之类的操作,很HTML Table!

好了,下面贴一段代码,虽然是网上抄来的,我只是省得以后到处找,大家也难得到这里来,看到了这篇文章,有兴趣就可以拿去看吧

  workbook=Workbook.createWorkbook(os);
