elementUI table 数组中各项加逗号隔开

js处理

//this.newTableData 数组 
            this.newTableData.map((item,index)=>{
                //item.label 数组
                if(item.label){
                    item.label = item.label.join('，');
                }
            })

element UI table 中用插槽实现：

?

1 2 3 4 5 6 7 8 9 10

<el-table-column prop="label" label="客群标签">                     <template slot-scope="scope">                         <div class="label-ceil">                             <div v-for="(item,ind) in scope.row.label" :key="ind">                                 <span v-if="ind+1 == scope.row.label.length">{{item}} </span>                                 <span v-else>{{item}},</span>                             </div>                         </div>                     </template>                 </el-table-column>

　　数组最后一个不加逗号
