    exportToExcel() {
      // 假设你有一个表格数据的数组
      // const data = [
      //  ["姓名", "年龄", "职业"],
      //  ["Alice", 28, "Engineer"],
      //  ["Bob", 22, "Designer"]
      // ];

        { 
          hangingTime: "2025-01-20 16:00",
          codes: ["AB51KB16002534", "AB51KB16002278", "AB51KB16002604", "AB51KB16002284", "AB51KB16002570",…]

        {
          hangingTime: "2025-01-21 16:00",

        },
        ...
      ]
      res.data.map((io) => {
         let newArray = io['codes'].map(item => [item])
         // console.log(newArray)
         data.push(['阳极下挂时间' + io.hangingTime], ['产品流水号'], ...newArray)
      })
      console.log(data)

      // 将数据转换为工作表
      const worksheet = XLSX.utils.aoa_to_sheet(data);
     
      // 创建工作簿并添加工作表
      const workbook = XLSX.utils.book_new();
      XLSX.utils.book_append_sheet(workbook, worksheet, 'Sheet1');
     
      // 生成Excel文件
      const excelBuffer = XLSX.write(workbook, { bookType: 'xlsx', type: 'array' });
     
      // 使用blob和FileReader创建一个Blob URL
      const dataBlob = new Blob([excelBuffer], { type: 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet;charset=UTF-8' });
      const blobUrl = window.URL.createObjectURL(dataBlob);
     
      // 使用saveAs下载文件
      saveAs(dataBlob, 'export.xlsx');
     
      // 清理
      window.URL.revokeObjectURL(blobUrl);
    }
  }
};
</script>
