但是错误的效果：
代码：
infoChange() {if (this.info.id) {this.loading= true;var param = {id: this.info.id}getList(param).then(res => {this.info.list = res.rows; //整理格式...一顿数据操作，这里忽略if (this.info.list && this.info.list.length > 0) {//TODO 数据选择后回显this.$refs.multipleTable.clearSelection()var numbers = this.info.changeNumbers.split(',');if (numbers && numbers.length > 0) {numbers.forEach(item => { //numbers：选择行的不重复的字段，比如主键this.info.list.forEach(row => {// this.info.list：table中绑定的参数if (item == row.assetNumber) {//table数据回显this.$nextTick(() => {//multipleTable：table的ref定义名this.$refs.multipleTable.toggleRowSelection(row, true);});}});})}this.loading= false;}}).catch(() => {this.loading= false;});}},经过查询，是loading造成的，将loading去掉或者提前即可。
修改后的代码：
infoChange() {if (this.info.id) {this.loading= true;var param = {id: this.info.id}getList(param).then(res => {this.info.list = res.rows; //整理格式...一顿数据操作，这里忽略if (this.info.list && this.info.list.length > 0) {this.loading= false; //!!!!!!!!!!!!将loading提前!!!!!!!!!!!!!//TODO 数据选择后回显this.$refs.multipleTable.clearSelection()var numbers = this.info.changeNumbers.split(',');if (numbers && numbers.length > 0) {numbers.forEach(item => { //numbers：选择行的不重复的字段，比如主键this.info.list.forEach(row => {// this.info.list：table中绑定的参数if (item == row.assetNumber) {//table数据回显this.$nextTick(() => {//multipleTable：table的ref定义名this.$refs.multipleTable.toggleRowSelection(row, true);});}});})}}}).catch(() => {this.loading= false;});}},得到想要的效果：
