  jsp页面上的代码如下:
 response.setContentType("application/vnd.ms-excel;charset=GBK");
   String filename = new String(("excel名称.xls").getBytes(),
     "ISO-8859-1");
   response.setHeader("Content-Disposition", "attachment;"
     + " filename=" + filename);
    <%
    JavaBean bean = new JavaBean();
     bean .loadDataToExcel(response);
  %>
  JavaBean 页面上的代码如下:
   
  public boolean loadDataToExcel(HttpServletResponse response,
   List items) {
    boolean flag = false;
    try {
   WritableWorkbook wwb = Workbook.createWorkbook(response
     .getOutputStream());
   WritableSheet asheet = wwb.createSheet("处理信息统计表", 52);
   // 定义一个新字体,参数说明:字体,大小,格式,是否斜体,颜色(默认黑色)
   WritableFont wfc = new WritableFont(WritableFont.ARIAL, 12,
     WritableFont.BOLD, false);
   // 定义一个新字体,参数说明:字体,大小,格式,是否斜体,颜色(默认黑色)//不加粗
   WritableFont wf = new WritableFont(WritableFont.ARIAL, 12,
     WritableFont.NO_BOLD, false);
   // 设置单元格格式
   WritableCellFormat wchB = new WritableCellFormat(wfc);
   // 使单元格居中
   wchB.setAlignment(Alignment.CENTRE);
   // 设置制表单位&制表日期格式
   WritableCellFormat date = new WritableCellFormat(wf);
   // 设置表头格式
   WritableCellFormat tTitle = new WritableCellFormat(wf);
   tTitle.setAlignment(Alignment.CENTRE);
   tTitle.setVerticalAlignment(VerticalAlignment.CENTRE);
   tTitle.setWrap(true);
   tTitle.setBorder(Border.ALL, BorderLineStyle.THIN);
   // 设置数据显示格式
   WritableCellFormat data = new WritableCellFormat(wf);
   data.setBorder(Border.ALL, BorderLineStyle.THIN);
   // data.setb
   // 分别设置单元格的高度&宽度

   asheet.setColumnView(0, 12);
   asheet.setColumnView(1, 12);
   asheet.setColumnView(2, 8);
   asheet.setColumnView(3, 8);
   asheet.setColumnView(4, 8);
   asheet.setColumnView(5, 8);
   asheet.setColumnView(6, 8);
   asheet.setColumnView(7, 7);
   asheet.setColumnView(8, 7);
   asheet.setColumnView(9, 7);
   asheet.setColumnView(10, 7);
   asheet.setColumnView(11, 7);
   asheet.setColumnView(12, 7);
   asheet.setColumnView(13, 7);
   asheet.setColumnView(14, 7);

   /* 开始写入xls文件 */
   // 导出excel文件标题
   Label labelC = new Label(0, 0, "处理信息统计表", wchB);
   asheet.addCell(labelC);
   // 合并第一行16个单元格为1个作为标题栏
   asheet.mergeCells(0, 0, 15, 0);
   // 设置表头
   labelC = new Label(0, 1, "预报信息", tTitle);
   asheet.addCell(labelC);
   asheet.mergeCells(0, 1, 3, 1);

   labelC = new Label(0, 2, "检查场", tTitle);
   asheet.addCell(labelC);

   labelC = new Label(1, 2, "车型", tTitle);
   asheet.addCell(labelC);

   labelC = new Label(2, 2, "车号", tTitle);
   asheet.addCell(labelC);

   labelC = new Label(3, 2, "轴位及左右", tTitle);
   asheet.addCell(labelC);

   labelC = new Label(4, 1, "作业场处理信息", tTitle);
   asheet.addCell(labelC);
   asheet.mergeCells(4, 1, 15, 1);

   labelC = new Label(4, 2, "预警级别", tTitle);
   asheet.addCell(labelC);

   labelC = new Label(5, 2, "检查时间", tTitle);
   asheet.addCell(labelC);

   labelC = new Label(6, 2, "车次", tTitle);
   asheet.addCell(labelC);

   labelC = new Label(7, 2, "编组", tTitle);
   asheet.addCell(labelC);

   labelC = new Label(8, 2, "顺位", tTitle);
   asheet.addCell(labelC);

   labelC = new Label(9, 2, "轮位", tTitle);
   asheet.addCell(labelC);

   labelC = new Label(10, 2, "轴号", tTitle);
   asheet.addCell(labelC);

   labelC = new Label(11, 2, "故障原因", tTitle);
   asheet.addCell(labelC);

   labelC = new Label(12, 2, "实际测量数据", tTitle);
   asheet.addCell(labelC);

   labelC = new Label(13, 2, "测量人", tTitle);
   asheet.addCell(labelC);

   labelC = new Label(14, 2, "复测人", tTitle);
   asheet.addCell(labelC);

   labelC = new Label(15, 2, "处理方式", tTitle);
   asheet.addCell(labelC);
   wwb.write();
   wwb.close();
   flag = true;
  } catch (Exception e) {
   flag = false;
   e.printStackTrace();
  }
  return flag;
 }
注:1.   说明asheet.mergeCells(列1, 行1, 列2, 行2)合并单元格,起始都是0
     2 .  在Bean中需要导入两个jar包servlet.jar和jxl.jar
