vxe-grid 在高级导出窗口中如何自定义模板，扩展更多功能

官网文档：vxetable.cn 高级导出弹窗中使用自定义模板

由于 vxe-table 本身就支持导出功能，所以使用自带的导出，但是自带的导出不能满足需求时，可能需要增加一些功能，这时候就可以使用自定义插槽来实现。vxe-table 的强大之处就是基本上任何功能都能自定义扩展。

说明

先来看一下默认的导出窗口

接下详细说明各个插槽的用法，非常灵活： top 顶部插槽 bottom 底部插槽 footer 尾部按钮插槽 default 自定义整个弹窗内容插槽

top 顶部插槽

      </template>
    </vxe-grid>
