当数据包含空值时，如何按长度对Antd表数据进行排序

import { Table } from 'antd';

const data = [
  { id: 1, name: 'John', age: 25 },
  { id: 2, name: 'Alice', age: null },
  { id: 3, name: 'Bob', age: 30 },
];

const columns = [
  { title: 'ID', dataIndex: 'id', sorter: (a, b) => a.id - b.id },
  { title: 'Name', dataIndex: 'name', sorter: (a, b) => a.name.localeCompare(b.name) },
  { title: 'Age', dataIndex: 'age', sorter: (a, b) => {
    // 处理空值情况
    if (a.age === null && b.age === null) {
      return 0;
    } else if (a.age === null) {
      return 1;
    } else if (b.age === null) {
      return -1;
    }
    return a.age - b.age;
  }},
];

const App = () => {
  return <Table dataSource={data} columns={columns} />;
};

export default App;
