如下代码,将title的参数设置为null即可

ExportParams exportParams  = new ExportParams(null, "delivery", ExcelType.XSSF);
        exportParams.setStyle(ExcelStyleUtil.class);
        Workbook workbook = ExcelExportUtil.exportBigExcel(exportParams,
                DeliveryScheduleVoPlus.class,
                excelExportServer,
                null);
