[Vue warn]: Property or method "id" is not defined on the instance but referenced during render. Make sure that this property is reactive, either in the data option, or for class-based components, by initializing the property. See: https://vuejs.org/v2/guide/reactivity.html#Declaring-Reactive-Properties.

el-table 指定 row-key的时候，使用“:row-key="id"”的时候就会出现些错误，这时它会认为“id”是一个变量或方法，而我没有定义；
我为什么要使用“:row-key="id"”呢？因为不加冒号的时候，id字段本身是数字类型，它会默认给转换为字符串类型。
