Two column wide portlets for sortable

Two column wide portlets for sortable

Does anybody know how to create a two column wide portlet in a two column jQuery UI sortable setup?

I need to be able to mix one column wide portlets with two column wide portlets.  Currently if I add a two column wide portlet it floats on top of the 2nd column portlets and they do not move out of the way as desired.

Any ideas?
