## 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` 。
**注意,此示例使用 [模拟接口 ](https://randomuser.me ),展示数据可能不准确,请打开网络面板查看请求。**

## 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.**
```jsx
import { Table } from 'antd';
import reqwest from 'reqwest';
const columns = [
{
title: 'Name',
dataIndex: 'name',
sorter: true,
render: name => `${name.first} ${name.last}` ,
width: '20%',
},
{
title: 'Gender',
dataIndex: 'gender',
filters: [
{ text: 'Male', value: 'male' },
{ text: 'Female', value: 'female' },
],
width: '20%',
},
{
title: 'Email',
dataIndex: 'email',
},
];
const getRandomuserParams = params => ({
results: params.pagination.pageSize,
page: params.pagination.current,
...params,
});

state = {
