JAVA EXCEL API(jxl)简介
Java Excel是一开放源码项目，通过它Java开发人员可以读取Excel文件的内容、创建新的Excel文件、更新已经存在的Excel文件。使用该 API非Windows操作系统也可以通过纯Java应用来处理Excel数据表。因为是使用Java编写的，所以我们在Web应用中可以通过JSP、 Servlet来调用API实现对Excel数据表的访问。http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif提供以下功能：
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif * 从Excel 95、97、2000等格式的文件中读取数据；
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif * 读取Excel公式（可以读取Excel 97以后的公式）；
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif * 生成Excel数据表（格式为Excel 97）；
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif * 支持字体、数字、日期的格式化；
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif * 支持单元格的阴影操作，以及颜色操作；
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif * 修改已经存在的数据表；
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif * 能够读取图表信息
