Django Datatables view

Im trying to convert my tables in my django app to datatables using django-tables2.

Im my campaigns.py view I have:

class CampaignListView(FacebookAdInit):
    """ CampaignListView for viewing all the campaigns"""

    def get(self, request, *args, **kwargs):
        ad_account = self.get_ad_account(kwargs.get('ad_account_id'))

        campaigns = self.get_campaigns(ad_account.get('id')) \
            if ad_account else None
        context = {'campaigns': campaigns, 'ad_account': ad_account}

        return render(request, 'app/campaigns/index.html', context)

Im my campaigns/index.html I have:

{% extends "app/empty_page.html" %}
{% load render_table from django_tables2 %}
{% block content %}
            {% if ad_account %}
                        {% render_table context  %}
            {% endif %}

{% endblock %}

However this gives me the error: Expected table or queryset, not 'str'. ANy help will be greately appreciated.

Right now I generate the table using this piece of code:

                <table class="table table-bordered table-striped" id="campaigns">
                    <thead>
                    <tr>
                        <th> #</th>
                        <th> Campaign Name</th>
                        <th> Campaign Objective</th>
                        <th> Campaign Effective Status</th>
                    </tr>
                    </thead>
                    <tbody>
                    {% for campaign in campaigns %}
                        <tr>
                            <td> {{ forloop.counter }} </td>
                            <td>
                                <a href="/ad_accounts/{{ ad_account.id }}/campaigns/{{ campaign.id }}/ad_sets">
                                    {{ campaign.name }} </a>
                            </td>
                            <td> {{ campaign.objective }}</td>
                            <td> {{ campaign.effective_status }} </td>
                        </tr>
                    {% endfor %}
                    </tbody>
                </table>
