先看效果图

实现流程

整个过程可以分为三大步：

• 设计表头格式
• 根据表头对应的key填充数据
• 根据表头和数据导出Excel

实现代码

根据表头和数据导出Excel

  			// 设计表头格式
            List<ExcelExportEntity> callTableHeaderList = getExportRebateOffsetTableHeader();

            // 查询数据
            List<RebateOffsetVO> list = rebateOffsetList(request);

            // 根据表头对应的key填充数据
            List<Map<String, Object>> callRecordList = getExportRebateOffsetCallRecord(list);

            ExportParams exportParams = new ExportParams("title", DownloadTypeEnum.REBATE_OFFSET.getMeaning());
            exportParams.setType(ExcelType.HSSF);
            exportParams.setStyle(ExcelStyleHandler.class);
            // 根据表头和数据导出Excel
            Workbook workbook = ExcelExportUtil.exportExcel(exportParams, callTableHeaderList, callRecordList);

表头格式
