Django如何使用下拉菜单筛选表格？

from django.db import models

class Product(models.Model):
    category = models.CharField(max_length=100)
    # 其他字段...

from django import forms
from .models import Product

class ProductFilterForm(forms.ModelForm):
    class Meta:
        model = Product
        fields = ['category']

from django.shortcuts import render
from .forms import ProductFilterForm
from .models import Product

def filter_table(request):
    form = ProductFilterForm(request.GET)
    if form.is_valid():
        category = form.cleaned_data['category']
        filtered_products = Product.objects.filter(category=category)
    else:
        filtered_products = Product.objects.all()
    
    return render(request, 'filter_table.html', {'form': form, 'products': filtered_products})

<form method="get" action="{% url 'filter_table' %}">
    {{ form.as_p }}
    <button type="submit">筛选</button>
</form>

<table>
    <thead>
        <tr>
            <th>产品类别</th>
            <!-- 其他表头... -->
        </tr>
    </thead>
    <tbody>
        {% for product in products %}
        <tr>
            <td>{{ product.category }}</td>
            <!-- 其他表格内容... -->
        </tr>
        {% endfor %}
    </tbody>
</table>
