I've solved this in the past by creating this filter:
==========================================
from itertools import islice
def columnize(data, args="2"):
if ',' in args:
columns, padding = args.split(',', 1)
columns = int(columns)
else:
columns = int(args)
padding = ""
i = iter(data)
while True:
data = list(islice(i, columns))
ld = len(data)
if not ld: break
if ld <> columns:
data.extend([padding] * (columns - ld))
yield data
==========================================
and then, after registering it as a filter[1], using it like this:
-------------------------------------------------
<table>
{% for myrow in data|columnize:"3, " %}
<tr>
{% for value in myrow %}
<td>{{ value }}</td>
{% endfor %}
</tr>
{% endfor %}
</table>
or
<table>
{% for thing in my_queryset|columnize %}
<tr>
{% for value in myrow %}
<td>
{% if value %}
<b>{{ value.name }}:</b>
{{ value.other_field }}
{% else %}
{% endif %}
</td>
{% endfor %}
</tr>
{% endfor %}
</table>
-------------------------------------------------
My original can be found here[2] but I think this version is a
little easier to understand than the original.
Hope this helps,
