I think this is a good idea. I would suggest doing it by adding display: 
table-column-header-group and table-column-footer-group with the equivalent 
semantics that the row versions have (namely, changing the order of the 
rendering of the respective columns so that they are at the start/end of the 
table respectively).

In practice, though, it won't do what you are asking for. CSS doesn't actually 
use the header and footer groups to control where the header and footer rows 
repeat, only the order in which they appear in the flow. Repeating on a 
continuous medium would be done using overflow:scroll on the body group that 
they sandwich, and means that what you are asking for can already be done in 
CSS2. Repeating of table rows (columns) on a paged medium is currently under- 
defined in CSS2.
