## zh-CN

通过 `rowSelection.selections` 自定义选择项，默认不显示下拉选项，设为 `true` 时显示默认选择项。

## en-US

Use `rowSelection.selections` custom selections, default no select dropdown, show default selections via setting to `true`.

```jsx
import { Table } from 'antd';

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

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

class App extends React.Component {
  state = {
    selectedRowKeys: [], // Check here to configure the default column
  };

  onSelectChange = selectedRowKeys => {
    console.log('selectedRowKeys changed: ', selectedRowKeys);
    this.setState({ selectedRowKeys });
  };
