[Answered ]-Simple Math in Django template

You don’t need to do maths for this. The page object already gives you the relevant information: start_index and end_index.

So:

{% with table.page as page %}
Showing {{ page.start_index }} - {{ page.end_index }} of {{ page.paginator.count }}
{% endwith %}

Plus, you can use page.has_other_pages to determine if there are other pages, rather than your complex logic comparing the total with the current count.

See the pagination docs.
