Well I'd say it's definitely doable, but firstly you'd have to define the requirements. If you sort on a column and one row doesn't have that column, because another column extends into it, what happens? Similarly how do you deal with row spans, are they teated as on row, which row takes precendence in the sort etc?

Once you know that it's just a question of churning out the code which is going to fairly time consuming I'd have thought. I don't think this is a thirty minute job by any means.
