在我们实际的开发中，表现层的解决方案虽然有多样，但是IE浏览器已成为最多人使用的浏览器，因为大家都用Windows。在企业办公系统中，常常有客户这样子要求：你要把我们的报表直接用Excel打开(电信系统、银行系统)。或者是：我们已经习惯用Excel打印。

Apache的Jakata项目的POI子项目，目前比较成熟的是HSSF接口，处理MSExcel对象。它不象我们仅仅是用csv生成的没有格式的可以由Excel转换的东西，而是真正的Excel对象，你可以控制一些属性如sheet,cell等等。

-In our actual development, the presentation layer solutions, though there are diverse, but the IE browser has become the most widely used browser, since we all use Windows. Office systems in the enterprise, often a customer requirement like this: you want us to open the report directly in Excel (telecommunications systems, banking systems). Or: We have become accustomed to using Excel to print. Apache' s POI project Jakata sub, is more mature now HSSF interface, processing MSExcel object. It' s not like we just did not use the csv format generated by Excel converter things, but really the Excel object, you can control some of the properties such as sheet, cell, and so on.
