1.7.7

Environment

Windows, Chrome, Vue 2.6.12

Reproduction link

Steps to reproduce

transfer dataSource 中没有 key，但是定义了 row-key 指定了唯一标识，依然会打印警告信息

What is expected?

不要告警

What is actually happening?

控制台打印警告信息

---

datasource 数据结构中没有 key 属性，和服务端交互式，会提交 datasource 中选中的数据，所以不想额外添加这个 key。现在控制台有警告，不影响正常使用，但是强迫症很难受
