[Fixed]-Show div only if content is found from database

I would probably do something like this in your view

user_data.all = [user_data.x, user_data.y, ...]

user_data.any = any(user_data.all)

in the template

{% if user_data.any %}
{% for elem in user_data.all %}
<tr>
<th>{{ elem.title }}</th>
<td>{{ elem.data }}</td>
</tr>
{% endfor %}
{% endif %}

obviously that will only work if each element has.title and .data – but you could add a property to each existing model to produce that data
