ant-design-vue弹窗可拖动版本： ant-design-vue 1.6.2
效果（按住标题栏拖动，拖动超出窗⼝会⾃动出现滚动条）：
组件⽂件结构：
index.vue
（需要注意的是footer和title的处理，其他的props都是⼀致的）
<template>
<a-modal
:class="[modalClass, simpleClass]"
:visible="visible"
v-bind="$props"
:footer="null"
:bodyStyle="{padding:0}"
@ok="handleOk"
@cancel="handleCancel">
<div class="ant-modal-body" :>
<slot></slot>
</div>
<div class="ant-modal-footer relative">
<slot name="footer"></slot>
</div>
<div v-if="!title && title !== ''" slot="title">
<slot name="title"></slot>
</div>
</a-modal>
</template>
