js判断哪行数据为空

 for (let i = 0; i < this.treasureList.conf.length; i++) {
                let { gift_id, gift_name, gift_price, rate } = this.treasureList.conf[i]
                if (!gift_id || !gift_name || !gift_price || !rate) {
                    this.$Message.error(`第${i + 1}行数据未填写完整！`);
                    return false;
                }
            }
