原因是开启多标签之后，所有页面默认都开启缓存了，所有必定要带有这个刷新功能

这个是8999付费版的带有刷新功能

这个是白嫖版，没有这个刷新

自己也研究了它多标签组件里的源码 src\components\MultiTab\MultiTab.vue 不知道怎么拓展有老哥做过这个能提供一下思路吗

<script>

      if (!val) {
        throw new Error(`multi-tab: open tab ${val} err`)

      this.activeKey = val
    }).$on('close', val => {
      if (!val) {
        this.closeThat(this.activeKey)
        return
