返回目录：excel表格制作
下面是我写的一个运用jxl生成Excel文件的方法
该方法接收一e68a84e8a2ade799bee5baa6339个保存MarkesData数据的ArrayList arlist和文件生成路径Path
通过取得arlist里的数据生成Excel文件
感觉应该是你想要的 我没调试过也许有错 你也可以根据你的需要进行修改^_^

问题描述不清楚，new File(文件e799bee5baa6e997aee7ad94e59b9ee7ad94361名);这样不可以吗?
你应该是想把这个字段写入excel文件中的一列吧?
Cell cell = row.createCell(1);
cell.setCellValue(new Date());
CreationHelper createHelper = wb.getCreationHelper();
CellStyle cellStyle = wb.createCellStyle();
cellStyle.setDataFormat(createHelper.createDataFormat().getFormat("yyyy-MM-dd"));
cell.setCellStyle(cellStyle);

这个我做奖金，考勤系统的时候经常用到，是一个636f7079e799bee5baa6e997aee7ad94330方法，希望能帮到你。
用的apache poi:
/**
* 将奖金列表转换为奖金报表
* @param bonus
* @return byte[]
*/
private byte[] mainProcessBonusListToReport(List<Bonus> bonuses){
HSSFWorkbook hssfWorkbook = new HSSFWorkbook();
HSSFSheet hssfSheet =hssfWorkbook.createSheet("总奖金报表单");
/*第一行单元格合并*/
hssfSheet.addMergedRegion(new CellRangeAddress(0, 0, 0, 12));
/*第一行*/
HSSFRow hssfRow = hssfSheet.createRow(0);
HSSFCell hssfCell=hssfRow.createCell(0);
hssfCell.setCellValue("派单业务考核记录");
/*第二行*/
hssfRow = hssfSheet.createRow(1);
/*列名*/
String[] titles = {"序号","工号","话务员姓名","规范奖考核","业务奖金","话务奖金","服务质量奖金","星级系数","组长津贴","总奖金","增资奖金","英语翻译","实发总奖金"};
/*for循环生成列名*/
for (int i = 0; i < titles.length; i++) {

hssfCell.setCellValue(titles[i]);
}
/*填充数据*/
