ant-desin-vue——table全选时自定义的禁用行也被选上，且最后一行不选中问题

错误效果（序号1是获取数据后，初始化禁用的项）：                                                        正确效果：

                                                                                                     

原因：未给数据指定key

    <a slot="name" slot-scope="text">{{ text }}</a>
