以下代码实现:

ExcelUtil.excelHeadMaintenanceRepair(sheet, cellStyle);
Row row = sheet.createRow(rowNum);
ExcelUtil.setMaintenanceRepair(vehicleMaintenanceDto, row);

ExcelUtil的工具类实现
ExcelUtil.excelHeadMaintenanceRepair(sheet, cellStyle);方法实现

public static void excelHeadMaintenanceRepair(XSSFSheet sheet, CellStyle cellStyle) {
        cellStyle.setFillForegroundColor(IndexedColors.TEAL.getIndex());
        Row row = sheet.createRow(0);

        Cell cel0 = row.createCell(0);
        cel0.setCellStyle(cellStyle);
        cel0.setCellValue("流水号");

        Cell cell = row.createCell(1);
        cell.setCellStyle(cellStyle);
        cell.setCellValue("车牌号");

        Cell cel2 = row.createCell(2);
        cel2.setCellStyle(cellStyle);
        cel2.setCellValue("维修保养类型");

        Cell cel3 = row.createCell(3);
        cel3.setCellStyle(cellStyle);
        cel3.setCellValue("车辆行驶里程");

        Cell cel4 = row.createCell(4);
        cel4.setCellStyle(cellStyle);
        cel4.setCellValue("费用总计");

        Cell cel5 = row.createCell(5);
        cel5.setCellStyle(cellStyle);
        cel5.setCellValue("收票状态");

        Cell cel6 = row.createCell(6);
        cel6.setCellStyle(cellStyle);
        cel6.setCellValue("维保时间");

        Cell cel7 = row.createCell(7);
        cel7.setCellStyle(cellStyle);
        cel7.setCellValue("维修厂名称");

        Cell cel8 = row.createCell(8);
        cel8.setCellStyle(cellStyle);
        cel8.setCellValue("操作人");

        Cell cel9 = row.createCell(9);
        cel9.setCellStyle(cellStyle);
        cel9.setCellValue("创建时间");
