将Java类转换为List<List<String>>以在表中显示

public class Person {
    private String name;
    private int age;
    private String gender;

    // 构造函数和getter/setter方法省略
}

List<List<String>> tableData = new ArrayList<>();

List<Person> personList = new ArrayList<>();
// 添加Person对象到personList省略

for (Person person : personList) {
    List<String> rowData = new ArrayList<>();
    rowData.add(person.getName());
    rowData.add(String.valueOf(person.getAge()));
    rowData.add(person.getGender());
    tableData.add(rowData);
}
