<el-table-column align="left" label="姓名" show-overflow-tooltip :key="tableKey"><template slot-scope="scope"><el-select placeholder="请选择" :disabled="!saveButton" v-model="scope.row.firemans" @change="changeFiremans" filterable multiple :key="scope.$index" style="width: 100%"><el-option v-for="item in getPostMember(scope.row)" :key="item.memberUuid" :label="item.memberName" :value="item.memberUuid"></el-option></el-select></template></el-table-column>

需要在el-table-column上添加:key="tableKey"

tableKey

  data () {return {tableKey: Math.random()}}

el-select添加change事件修改tableKey

changeFiremans() {this.tableKey = Math.random()}
