## zh-CN

这个例子通过简单的 ajax 读取方式，演示了如何从服务端读取并展现数据，具有筛选、排序等功能以及页面 loading 效果。开发者可以自行接入其他数据处理方式。

另外，本例也展示了筛选排序功能如何交给服务端实现，列不需要指定具体的 `onFilter` 和 `sorter` 函数，而是在把筛选和排序的参数发到服务端来处理。

当使用 `rowSelection` 时，请设置 `rowSelection.preserveSelectedRowKeys` 属性以保留 `key`。

## en-US

This example shows how to fetch and present data from a remote server, and how to implement filtering and sorting in server side by sending related parameters to server.

Setting `rowSelection.preserveSelectedRowKeys` to keep the `key` when enable selection.

**Note, this example use [Mock API](https://randomuser.me) that you can look up in Network Console.**
