Vue+jquery实现表格指定列的文字收缩的示例代码

<el-table-column width="250" align="center" label="比较基准">
 <template scope="scope">
  <span v-if="isAllTxt">{{getShortStr(scope.row.benchmark)}}</span>
  <span v-else>{{scope.row.benchmark}}</span>
  <i @click="changeTxt" style="margin-left:8px;color: #20a0ff;" class="el-icon-more"></i>
 </template> 
</el-table-column>

changeTxt(ref) {
  ref.text(XXX);
}

<span ref="txt">{{getShortStr(scope.row.benchmark)}}</span>

<el-table-column width="250" align="center" label="比较基准"> 
 <template scope="scope">
   <span :id="scope.row.id">{{getShortStr(scope.row.benchmark)}}</span>
  <i v-if="scope.row.benchmark.length>20" @click="changeTxt(scope.row.benchmark,scope.row.id)" style="margin-left:8px;color: #20a0ff;" class="el-icon-more">
  </i>
 </template>
</el-table-column>

// changeTxt方法：
  changeTxt(txt,id) {
   this.isAllTxt = !this.isAllTxt;
   if(this.isAllTxt){
    $('#'+id).text(txt);
   }else{
    $('#'+id).text(this.getShortStr(txt));
   }
  }

// getShortStr 方法
getShortStr(txt_origin) {
 if(txt_origin.length > 20){
  return txt_origin.substring(0,20);
 }else{
  return txt_origin;
 }
}
