You can create columns without values.
Are you talking about reading them back through the API ?
I would suggest looking at your data model to see if there is a better way to support your read patterns.

It would be definetely useful to be able to have columns (or super columns) names WITHOUT their values. If these ones are pretty big or if there are a lot of columns, that would generate traffic not necessarily needed (if in the end you are just interrested by some column).
Moreover it doesn't seem to be a feature too difficult to implement (well, I think...)
