固定列是通过把该列克隆一份来实现的（具体可参考 https://zhuanlan.zhihu.com/p/33280304 ），因此会有两个 Popover 实例，在使用v-model 控制显示与隐藏的情况下确实会发生同步现象。目前没有什么好方法，可以稍微 hack 一下：https://jsfiddle.net/leopoldthecuber/m417c85a/39/

@Leopoldthecoder 你好，我遇到了同样的问题，但是你的hack连接打不开了，请问你的解决方法是什么

If there is a fixed column, this situation will happen. It doesn't matter whether the fixed column has a el-popover or not. See this demo:

I put el-popover in the control column though address column is fixed.

在数据渲染后，找到多出来的popover隐藏起来，直接操作dom比较暴力。
不知道有没有更好的办法
