`render_table` error with `with_entities` query filter

Hello! Thanks for this beautiful library :)

I got an unexpected error when trying to use the table utility. Here is some context:

**vue:**

```python
def board():
profiles = models.Profile.query.filter(
models.db.or_(
models.Profile.status==models.Profile.REQUEST,
models.Profile.status==models.Profile.BLOCKED,
models.Profile.status==models.Profile.UNCLAIMED,
)).order_by(models.Profile.status.desc())
profiles = profiles.with_entities(models.Profile.uuid, models.Profile.username).all()
events = models.History.query.all()
return flask.render_template("moderation_home.html", events=events,
profiles=profiles)

```

template (working :green_circle:)

```twig

{% for profile in profiles %}

{% endfor %}



{% trans %}UUID{% endtrans %}
{% trans %}username{% endtrans %}



{{ profile.uuid }}
{{ profile.username }}

```

**template (not working :red_circle:)**

```twig
{{ render_table(profiles, primary_key='uuid') }}
```

**error:**

```log
Traceback (most recent call last):
File "lib/python3.12/site-packages/sqlalchemy/engine/result.py", line 199, in _key_not_found
self._key_fallback(key, None)
File "lib/python3.12/site-packages/sqlalchemy/engine/result.py", line 138, in _key_fallback
raise KeyError(key) from err
KeyError: '__table__'

The above exception was the direct cause of the following exception:

```

I double checked that `uuid` is indeed the primary key, but the result is the same with or without `primary_key='uuid'`.

The error appeared after I introduced

`profiles = profiles.with_entities(models.Profile.uuid, models.Profile.username).all()`

in my request. Without that column filter, everything works very well.
