## zh-CN

选择后进行操作，完成后清空选择，通过 `rowSelection.selectedRowKeys` 来控制选中项。

## en-US

To perform operations and clear selections after selecting some rows, use `rowSelection.selectedRowKeys` to control selected rows.

```tsx
import React, { useState } from 'react';
import { Table, Button } from 'antd';
import type { ColumnsType } from 'antd/lib/table';

interface DataType {
  key: React.Key;
  name: string;
  age: number;
  address: string;
}

const columns: ColumnsType<DataType> = [
  {
    title: 'Name',
    dataIndex: 'name',
  },
  {
    title: 'Age',
    dataIndex: 'age',
  },
  {
    title: 'Address',
    dataIndex: 'address',
  },
];

const data: DataType[] = [];
for (let i = 0; i < 46; i++) {
  data.push({
    key: i,
    name: `Edward King ${i}`,
    age: 32,
    address: `London, Park Lane no. ${i}`,
  });
}

const App: React.FC = () => {
  const [selectedRowKeys, setSelectedRowKeys] = useState<React.Key[]>([]);
  const [loading, setLoading] = useState(false);

  const start = () => {
    setLoading(true);
    // ajax request after empty completing
    setTimeout(() => {
      setSelectedRowKeys([]);
      setLoading(false);
    }, 1000);
  };

  const onSelectChange = (newSelectedRowKeys: React.Key[]) => {
    console.log('selectedRowKeys changed: ', selectedRowKeys);
    setSelectedRowKeys(newSelectedRowKeys);
  };

  const rowSelection = {
    selectedRowKeys,
    onChange: onSelectChange,
  };
  const hasSelected = selectedRowKeys.length > 0;

  return (
    <div>
      <div style={{ marginBottom: 16 }}>
        <Button type="primary" onClick={start} disabled={!hasSelected} loading={loading}>
          Reload
        </Button>
        <span style={{ marginLeft: 8 }}>
          {hasSelected ? `Selected ${selectedRowKeys.length} items` : ''}
        </span>
      </div>
      <Table rowSelection={rowSelection} columns={columns} dataSource={data} />
    </div>
  );

export default App;
