## 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`.

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

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

  const rowSelection: TableRowSelection<DataType> = {
    selectedRowKeys,
    onChange: onSelectChange,
    selections: [
      Table.SELECTION_ALL,
      Table.SELECTION_INVERT,
      Table.SELECTION_NONE,
      {
        key: 'odd',
        text: 'Select Odd Row',
        onSelect: changableRowKeys => {
          let newSelectedRowKeys = [];
          newSelectedRowKeys = changableRowKeys.filter((_, index) => {
            if (index % 2 !== 0) {
              return false;
            }
            return true;
          });
          setSelectedRowKeys(newSelectedRowKeys);
        },
      },
      {
        key: 'even',
        text: 'Select Even Row',
        onSelect: changableRowKeys => {
          let newSelectedRowKeys = [];
          newSelectedRowKeys = changableRowKeys.filter((_, index) => {
            if (index % 2 !== 0) {
              return true;
            }
            return false;
          });
          setSelectedRowKeys(newSelectedRowKeys);
        },
      },
    ],
  };

  return <Table rowSelection={rowSelection} columns={columns} dataSource={data} />;
};

export default App;
```
