                                margin-left: 0.06rem;

                            }
                        }
                        /* WebKit browsers */
                        ::-webkit-input-placeholder {
                            color: $color;
                            font-weight: bold;

                    }


<el-select v-model="valueGive[scope.$index]" @change="((val)=>{onGiveBtn(val, scope.row)})" placeholder="赠送">
           <el-option :key="0" :value="0" :label="'小可爱'"></el-option>
           <el-option :key="1" :value="1" :label="'大可爱'"></el-option>
           <el-option :key="2" :value="2" :label="'可爱多'"></el-option>
</el-select>

清空的方法：
this.valueval = []
