Can you explain it with a more explicit example? Not sure i understand what you said. Can you explain it with a more explicit example?

Often you need the opposite, especially if you have sorted data - say, list of countries. Basically, you will want just one row in a table where the first column has the first chunk of the list and so on.

My main point was to express the creation of a template filter, but your solution for the filter implementation code is by far simpler :) Thanks for the one liner.

fixed! :-)

Thanks. I want my tables to have the same number of columns on every row... # Still stuff missing? # see how many are missing and add empty elements to complete the row if len(row) > 0: remaining = len(row) to_add = cols - remaining for c in range(to_add): row.append([]) rows.append(row) return rows Perhaps by now there is a better way to do this, but I found it useful.
