如何使用apache-poi在列中显示对象

import org.apache.poi.ss.usermodel.*;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;

import java.io.FileOutputStream;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;

public class ApachePOIExample {
    public static void main(String[] args) {
        // 创建一个工作簿
        Workbook workbook = new XSSFWorkbook();
        
        // 创建一个工作表
        Sheet sheet = workbook.createSheet("Sheet1");
        
        // 创建对象列表
        List<Person> personList = new ArrayList<>();
        personList.add(new Person("John", 25));
        personList.add(new Person("Jane", 30));
        personList.add(new Person("Tom", 35));
        
        // 在列中显示对象
        int rowNum = 0;
        for (Person person : personList) {
            Row row = sheet.createRow(rowNum++);
            Cell cell1 = row.createCell(0);
            cell1.setCellValue(person.getName());
            Cell cell2 = row.createCell(1);
            cell2.setCellValue(person.getAge());
        }
        
        // 保存工作簿到文件
        try (FileOutputStream outputStream = new FileOutputStream("output.xlsx")) {
            workbook.write(outputStream);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

class Person {
    private String name;
    private int age;
    
    public Person(String name, int age) {
        this.name = name;
        this.age = age;
    }
    
    public String getName() {
        return name;
    }
    
    public int getAge() {
        return age;
    }
}
