This is a pretty straightforward example of grouping.  You will need to add the titles to your dataset in some way.  Ideally, it is already in your datasource.  If not, simply create a formula to calculate what the titles should be.  You can group on a formula (with certain restrictions, which shouldn't be a problem here).

Once you have your titles defined as a field, simply go into the Group Expert and create a group based on the titles.  Groups will come with their own headers and footers, which will allow you to put in your column headers.

Check out Chapter 3 of Brian's book for quite a bit of information on grouping.
