var keyMap = {
            deviceUid: "id",
            deviceType: "typeName",
            deviceCode: "code",
            deviceName: "name",
            deviceStatus: "status"
          };
          for (var i = 0; i < data.confList.length; i++) {
            var obj = data.confList[i];
            for (var key in obj) {
              var newKey = keyMap[key];
              if (newKey) {
                obj[newKey] = obj[key];
                delete obj[key];
              }
            }
          }
          console.log("array", data.confList);

或者重新建一个[]

然后重新push

let itemArr = [];
      this.deviceTableData_ys_true.map(item => {
        itemArr.push({
          deviceUid: item.id,
          deviceId: item.deviceId
        });
      });
