[antdv: Table] Each record in dataSource of table should have a unique `key` prop, or set `rowKey` of Table to an unique primary key

错误原因：表格中的表一条数据都应该有一个key或者rowkey

解决方法：

在设置table格式的位置加入:rowKey="(record,index)=>{return index}"，如下所示：

<a-table
  :columns="tableCols"
  :data-source="tableData"
  :rowKey="(record,index)=>{return index}"
>
  <a slot="a2" slot-scope="text">{{ text }}</a>
</a-table>
