如何在React Native中显示两列卡片？

import React from 'react';
import { View, StyleSheet, FlatList } from 'react-native';

const cardData = [
  { id: '1', title: 'Card 1', description: 'This is card 1' },
  { id: '2', title: 'Card 2', description: 'This is card 2' },
  // 更多卡片数据...
];

const Card = ({ title, description }) => (
  <View style={styles.card}>
    <Text style={styles.title}>{title}</Text>
    <Text>{description}</Text>
  </View>
);

const App = () => (
  <View style={styles.container}>
    <FlatList
      data={cardData}
      keyExtractor={(item) => item.id}
      numColumns={2}
      renderItem={({ item }) => (
        <Card title={item.title} description={item.description} />
      )}
    />
  </View>
);

const styles = StyleSheet.create({
  container: {
    flex: 1,
    padding: 10,
  },
  card: {
    flex: 1,
    margin: 5,
    padding: 10,
    backgroundColor: '#ebebeb',
    borderRadius: 5,
  },
  title: {
    fontWeight: 'bold',
    marginBottom: 5,
  },
});
