## 注意
|
||||
|
||||
按照 React 的[规范](http://facebook.github.io/react/docs/multiple-components.html#dynamic-children),所有的组件数组必须绑定 key。在 Transfer 中,`dataSource`里的数据值需要指定 `key` 值。对于 `dataSource` 默认将每列数据的 `key` 属性作为唯一的标识。
|
||||
|
||||
如果你的数据没有这个属性,务必使用 `rowKey` 来指定数据列的主键。
|
||||
```jsx
|
||||
// 比如你的数据主键是 uid
|
||||
return <Transfer rowKey={record => record.uid} />;
|
||||
```
