如何在react-native-paper的DataTable中更改表列宽度

import { DataTable } from 'react-native-paper';

render() {
  return (
    <DataTable>
      <DataTable.Header>
        <DataTable.Title>Name</DataTable.Title>
        <DataTable.Title flex={2}>Age</DataTable.Title>
        <DataTable.Title>City</DataTable.Title>
      </DataTable.Header>

      <DataTable.Row>
        <DataTable.Cell>John Doe</DataTable.Cell>
        <DataTable.Cell flex={2}>25</DataTable.Cell>
        <DataTable.Cell>New York</DataTable.Cell>
      </DataTable.Row>

      <DataTable.Row>
        <DataTable.Cell>Jane Smith</DataTable.Cell>
        <DataTable.Cell flex={2}>30</DataTable.Cell>
        <DataTable.Cell>Los Angeles</DataTable.Cell>
      </DataTable.Row>
    </DataTable>
  );
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    padding: 16,
    backgroundColor: '#fff',
  },
});
