bee-table 动态绑定列的问题

[JohnnieCai]

环境及版本信息

• tinper-bee 版本号:
  2.4.0

• 若使用单个组件，请标明该组件版本号：
  bee-table 2.2.61

• 当前项目中react的版本号：

• 所使用的操作系统：
  win10

• 所使用的浏览器：
  Chrome 85.0.4183.102

描述这个问题:

1、组件相关代码

代码粘贴区域

2、报错信息

在窗体加载时设置了默认column，选择导入文件后根据导入文件的列对column进行动态更新，更新后通过setState对column和data进行更新，通过跟踪发现render中的值是更新后的值，但是结果是table仍然只显示了默认的列和对应的数据

当前的行为：效果（可截图说明）及动作描述

期望的行为:

table能够根据更新后动态的列展示对应绑定的数据

异步更改column没有重现你说的问题，你可以给column赋个新值试下，比如column =Object.assign(column)再赋值给Table。

我是用的table，并且是在页面加载的时候已经加载完毕，然后点击页面上的按钮触发事件对table的列进行修改更新，不管是直接setState还是setTimeout界面上的列均不会再改变列，数据会改变。列使用的元素是title,dataindex,key,width，而且我用的是对数组进行push增加列对象不是减少，刚才试了下还是不行。

@JohnnieCai 像这样直接清空也不行吗：
