请问你是怎么保存的？？不是调用的baasData组件的saveData() 方法吗？？
如果是自己使用ajax调用的保存action
那么data组件中数据行的状态时没改变的！下次保存这些行数据会重复保存的！所以
如果完全自己实现！需要循环修改行的状态！

参考：

还有关于data组件的ＡＰＩ文档！

你应该调用的是ｄａｔａ组件的saveData() 方法！这个方法才会出来data组件中行的状态！
而你自己调用action ，行状态肯定不会自动修改的！你也可以使用代码实现，保存成功后，把行状态都变成none

那视频里的takeout  的demo是有问题的吗？我是参照那个视频做的开发。那里就是调用了save方法啊

如果是调用 data.saveData() 方法保存的数据！底层是已经实现了修改行状态的！
就看你是不是这样调用的了！
直接写takeout的action  save 也可以，但是要写在data的onCustomSave 事件中！
然后你直接调用 data.saveData()  就OK
