🧐[问题] EditableProTable 对操作行会对数据生成 index 为 key的脏key

提问前先看看：

### 🧐 问题描述
如官方示例所示，多出了一个index，这算是特性？还是算脏数据，如果我需要做form前后值比对，这个index对于我来说是没用的脏数据。。它只要操作过就给最终值加上index的key感觉也不是很合理？

### 💻 示例代码
无

### 🚑 其他信息


Start with the official EditableProTable example referenced in the report and compare form values before and after editing a row. Confirm when the index key is introduced and whether it is intended; done means the expected behavior and a verified resolution for the extra key are established.
