给你看看我以前servlet导出Excel的例子public void doGet(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        request.setCharacterEncoding("gbk");
        EmployeeVo employeeVo=new EmployeeVo();
         //»ñÈ¡Ô±¹¤±àºÅ
         employeeVo.setEmpCode(request.getParameter("empCode"));
         System.out.println("ÄãÒªµ¼³öµÄÔ±¹¤±àºÅΪ:"+request.getParameter("empCode"));
         //»ñÈ¡Ô±¹¤ÐÕÃû
         employeeVo.setEmpName(request.getParameter("empName"));
        
        //³õʼ»¯Service
        IEmployeeManageBs service=new EmployeeManageBs();
        //µôÓÃService
        List employeeList=service.queryByCondition(employeeVo);

Answer 2

对于这个字段（即在Excel中显示）比较多的 你可以先去定义个模板文件。。这样再用结合数据读取模板。这样就不会存在java类里面设置好多项的麻烦了、。。要修改直接改模板。

Answer 3

谢谢，birt是个报表插件，不是自己手动写的代码

Answer 4

 你这里说的修改模板，那不是得修改birt源代码的模板吗，但就算是修改了birt的里面的源代码，可对其它的导出又不适用了 

Answer 5

lz,你可以给报表的Layout prefrence属性，设置成auto Layout；并把每列的宽度设置的差不多。可能会好些。
对于，列比较多，导出在Excel中显示的时候，出现挤压正常的，顶多在Excel中将列拖的宽些就是了。
