iview table列表加塞2列数据

table表格里面的某列数据时从其他接口取出来的。

列如：

分区这列数据时不是table列表的 :data="historyData" 里面返回的，需要前面在赋值列表值前，赛到 this.historyData 里面；

下面是主要代码的逻辑：

    for(let i=0; i<result.length; i++){
        // let names = [];
        let idArry = result[i].areaIdList.split(',');
        for(let j=0; j<this.areaIdALLData.length; j++){
            idArry.map(v=>{
                if( v == this.areaIdALLData[j].id){
                    // names.push(this.areaIdALLData[j].name)
                    result[i].areaName += this.areaIdALLData[j].name + ','
                }
            })
            //  result[i].areaName = String(names);
        } 
         result[i].areaName = result[i].areaName.substring(0, result[i].areaName.length-1)
    }

    this.historyData = result;

这里还用到了一个  += 的用法，原因是因为  ： this.areaIdALLData[j].name，每回只能是一个值，

而：result[i].areaName  可能是1个，也可能是2个、3个...

所以这里用到了 += 

result[i].areaName += this.areaIdALLData[j].name + ','

这里塞了一个  逗号，可能会多赛一次，在每个值得最后面又赛了一个逗号，

处理方法：

result[i].areaName = result[i].areaName.substring(0, result[i].areaName.length-1)

完整代码如下：

  <div>
    12306
    <Table border :columns="columnsData" :data="historyData" width="800"></Table>
  </div>
</template>
