Answer 1

In the django template

#first we create the header of the table with the years
<tr class="first-table-row">
        # leave it blank so the first column is empty
        <th></th>
        #loop trough the items
        {% for i in bookdata %} 
           <th>{{i.year}}</th>
        {% endfor %}
</tr>
#loop trough the items again
{% for i in bookdata %}
       <td>{{i.point}}</td>
        # I don't know how your object is structured man please submit it so I can continue 
{% endfor %}
