You cannot append a variable onto a list variable to use its value as
an index into the list. columnumber is not an attribute of the type
list, nor is rownumber an attribute of the data list.
In addition, range is not a standard Django template tag, where did
you find that? As I mentioned, you cannot index the list variables,
therefore a range template tag would not do much good. Most of the
time, an iterator is more efficient than indexing into an array.
What I would do is this:
{% for d in data %}
{% for t in type %}
<td type="{{ t.0 }}">{{ d.0 }}</td><td type="{{ t.1 }}">{{ d.1 }}</
td><td type="{{ t.2 }}">{{ d.2 }}</td>
{% endfor %}
{% endfor %}
But since you already know the types of the three columns, I would
just go ahead and hard code them into the template.
