problems with table generation using nested forloop in django templates
This part is from views.py

    results=[(A,[stuObj1,stuObj2,stuObj3]),(B,[stuObj4,stuObj5,stuObj6]),(C,[stuObj7,stuObj8])]
    for tup in results:
        total = tot+len(tup[1])
    render_to_response(url,{'results':res , 'total':str(tot),})

this is template code:

    <th class="name">Name</th>
    <th class="id">Student ID</th>
    <th class="grade">Grade</th>
        {% for tup in results %}    
           {% for student in tup|last %}
               {% with forloop.parentloop.counter as parentid%}
               {% with forloop.counter as centerid%}
            <tbody class="results-body">
            <tr>
                <td>{{student.fname|lower|capfirst}} {{student.lname|lower|capfirst}}</td>
                <td>{{student.id}}</td>
                <td>{{tup|first}}</td>
            </tr>
           {% endfor %}
         {% endfor %}

Now the problems am having are 1. numbering the rows 
Here my problem is am not sure if i can do things like `total=total-1` in the templates to get the 
numbered rows like `<td>{{total}}</td>`
2.applying css to tr:ever or odd.
Whats happening in this case is everytime the loop is running the odd/even ordering is lost.
these seems related problems. Any ideas would be great :)
