TR, TH, TD was created but TABLE NOT - django

Question

i Need understand it but not be able to.
My ClassForm (in view):
class FormContact(forms.Form):
name = forms.CharField(label='Nome', max_length=100, required=False)
subject = forms.CharField(label='Assunto', max_length=100, required=False)
message = forms.CharField(label='Mensagem', widget=forms.Textarea, required=False)
My extended Template:
{% extends 'site.html' %}
{% load static %}
{% block content %}
<form class="contato" id="contato" action="{% url 'contato' %}" method="post">
<h1>Contato</h1>
{% csrf_token %}
{{ form }}
<input type="submit" value="Submit">
</form>
<script src="{% static 'js/form_contact.js' %}"></script>
{% endblock %}
Now,
in the navigator (inspector -> elements)
<form class="contato" id="contato" action="/contato/" method="post">
<h1>Contato</h1>
<input type="hidden" name="csrfmiddlewaretoken" value="???">
<label for="id_name">Nome:</label>
<input type="text" name="name" maxlength="100" id="id_name">
<label for="id_subject">Assunto:</label>
<input type="text" name="subject" maxlength="100" id="id_subject">
<label for="id_message">Mensagem:</label>
<textarea name="message" cols="40" rows="10" id="id_message"></textarea>
<input type="submit" value="Submit">
/form>
AND, in the navigator (Ctrl+U) View Code
<form class="contato" id="contato" action="/contato/" method="post">
<h1>Contato</h1>
<input type="hidden" name="csrfmiddlewaretoken" value="????">
<tr>
<th><label for="id_name">Nome:</label></th>
<td>
<input type="text" name="name" maxlength="100" id="id_name">
</td>
</tr>
<tr>
<th><label for="id_subject">Assunto:</label></th>
<td>
<input type="text" name="subject" maxlength="100" required id="id_subject">
</td>
</tr>
<tr>
<th><label for="id_message">Mensagem:</label></th>
<td>
<textarea name="message" cols="40" rows="10" required id="id_message"></textarea>
</td>
</tr>
<input type="submit" value="Submit">
</form>
My doubt is:
Why, in the Ctrl+U, was created the elements TR, TH and TD but TABLE not?
I can't understand it
It is this form same?
