antd table bug: rowSelection config type can't apply

Reproduction link

https://localhost

Steps to reproduce

const rowSelection = {
      type: "radio",
      selectedRowKeys,
      onChange: this.onSelectChange
}
<Table<TrainingDataColumn> scroll={{y: 290}} bordered={true} rowSelection={rowSelection} columns={this.columns} dataSource={formListData} />

What is expected?

table behavior normal and radio works right，not checkbox

What is actually happening?

Type '{ type: string; selectedRowKeys: number[]; onChange: (selectedRowKeys: any) => void; }' is not assignable to type 'TableRowSelection'.
Types of property 'type' are incompatible.
Type 'string' is not assignable to type '"radio" | "checkbox" | undefined'. TS2322
