Django template doesn't output values to HTML table cells

I have the following template:

 <table>
     <tr>
         <th>Monday</th>
        <th>Tuesday</th>
        <th>Wednesday</th>
        <th>Thursday</th>
        <th>Friday</th>
        <th>Saturday</th>
        <th>Sunday</th>
    </tr>

    {% for row in table %}
    <tr>
        {% for i in week_length %}
        <td>{{row.i}}</td>
        {% endfor %}
    </tr>
    {% endfor %}
</table>

And the following view:

def calendar(request):
    template_name = 'workoutcal/calendar.html'

    today_date = timezone.now()
    today_year = today_date.year
    today_month = today_date.month
    today_day = today_date.day

    table = maketable(today_date) # Creates something like: [[None, 1, 2, 3, 4, 5, 6],[7, 8, ...],...,[28, 29, 30, 31, None, None, None]]

    template = loader.get_template('workoutcal/calendar.html')

    #Workout.objects.filter("Workouts lie between certain dates")
    context = {
        'workout_list': Workout.objects.filter(date__year = today_year, date__month = today_month, date__day = today_day),
        'table': table, # The calendar
        'week_length': range(7),
    }
    return HttpResponse(template.render(context, request))

When I access the page (localhost:8000/workoutcal), nothing except for the table headers is output. It looks like this:

The table

inspecting the object

I can't figure out why Django is not putting my output into the cell. I want no output for elements of the list that are None, and then simply the element content (all are strings) in for all other elements. Any ideas?

You're iterating over the wrong thing. Your calendar is a list of lists; you should iterate over each row, then each column in that row. week_length is completely irrelevant.

{% for week in table %}
<tr>
    {% for day in week %}
    <td>{{ week }}</td>
    {% endfor %}
</tr>
{% endfor %}

You are not accessing the items in the row object correctly. They are at index i not at the attribute named i.

You could just do the following:

{% for i in row %}
    <td>{{ i }}</td>
{% endfor %}

Because row is the list of elements you want to access. This would avoid the need to pass the week_length variable.
