从网上下载jxl组件。然后用下面的方法即可//生成设备使用情况报表方法
  private void PrintExcal(String result) {
    try {
      WritableWorkbook workbook = Workbook.createWorkbook(new File(result));
      WritableSheet sheet = workbook.createSheet("First Sheet", 0);
      // 定义18号字体
      WritableFont arial18font = new WritableFont(WritableFont.ARIAL, 18);
      WritableCellFormat arial18format = new WritableCellFormat(arial18font);
      //定义14号字体
      WritableFont arial14font = new WritableFont(WritableFont.ARIAL, 14);
      WritableCellFormat arial14format = new WritableCellFormat(arial14font);      jxl.write.Label label = new jxl.write.Label(0, 1, "DCN设备使用情况月表",
                                                  arial18format);
      try {
        sheet.addCell(label);
        label = new jxl.write.Label(0, 3,
                                    MonthInputYear.getText() + "年" +
                                    MonthInputMonth.getText() + "月",
                                    arial14format);
        sheet.addCell(label);
        label = new jxl.write.Label(4, 3, "填表单位:" + EUSPDepName.getText(),
