如何使用Django中的按钮对表列进行排序

class Person(models.Model):
    name = models.CharField(max_length=100)
    age = models.IntegerField()

    class Meta:
        ordering = ['name']  # 设置默认按name字段排序

def person_list(request):
    sort_by = request.GET.get('sort_by')  # 获取排序参数
    if sort_by == 'name':
        persons = Person.objects.all().order_by('name')
    elif sort_by == 'age':
        persons = Person.objects.all().order_by('age')
    else:
        persons = Person.objects.all()

    context = {
        'persons': persons,
        'sort_by': sort_by
    }
    return render(request, 'person_list.html', context)

<table>
    <thead>
        <tr>
            <th>
                <a href="?sort_by=name">Name</a>
            </th>
            <th>
                <a href="?sort_by=age">Age</a>
            </th>
        </tr>
    </thead>
    <tbody>
        {% for person in persons %}
        <tr>
            <td>{{ person.name }}</td>
            <td>{{ person.age }}</td>
        </tr>
        {% endfor %}
    </tbody>
</table>
