Description: `<div ngFor="let item of pagetable.thead"> <div ngIf="item.action && item.action.length>0;">

    </div>
    <div *ngIf="item.action && item.action.length==0;">
      <el-table-column model-key={{item.key}} label={{item.name}}></el-table-column>
    </div>
  </div>

this.pagetable = { thead:[ { name:'姓名', key:'name', action:[] }, { name:'身份证号码', key:'pid', action:[] }, { name:'性别', key:'sex', action:[] }, { name:'操作', key:'opt', action:[ { label:'催办', value:'cuiban' }, { label:'编辑', value:'bianji' }, { label:'删除', value:'shanchu' } ] } ] } ` 使用ngIf就会满足条件就跳出，例如第一组数据满足就会跳出，然后再次循环，有多少个满足条件就会循环几次
