and design vue2版的table表格不能拖拽列的宽度，通过vue-draggable-resizable插件实现
我用的是and design 1.7.8的版本，先下插件

yarn add vue-draggable-resizable@2.1.0

我这版本的and design用最新3.0.0以上的插件会有问题，实现不了效果，换了低版本就没问题了
官方也有教使用方法，但会报错，按照官方的来写，需要把ResizeableTitle改成resizeableTitle这样就解决了最开始的报错

官方使用地址
下面是我封装的table公用组件，但是这样弄问题很多，在表格里加一下操作的时候很容易有问题，所以谨慎用这玩意
