[WSG] Markup for table with "groupings" - what's best

[spamdodger]

I need to write some markup for a data table that will look something  
like this sketch:
http://www.monkeypuzzle.net/testfiles/table.gif

The "grouping" rows (in blue) are really data columns (in another  
view of the same data) that a user can choose to "group" data by. My  
question really is how is this sort of table best structured?

Do I make each grouping a separate table, with the group name as  
perhaps <caption>?

Do I make each grouping a separate <tbody> within a table?

Do I  make each group heading (e.g.) "Name: Bango" a header row,  
along with the more traditional header row (Source, Date, etc.)

Do I use rowgroups?

I'm just not sure what the semantically correct approach would be -  
and appreciate any advice. Thanks!
