Vue2纯前端导出

 //导出
    exportExcel() {
      //构造数据

        ['姓名', '手机号码', '卡号', '身份等级'],

        }

      const arr = data2
      const newArray = arr.filter((subArr) => subArr[subArr.length - 1] === true)
      const newarraytwo = data1.concat(newArray)

      // const newarraytwo = newArray.insert(0, data1)
      // console.log(newarraytwo)
