We decided to provide the option to be able to call the "original" table editor of MOSS in addition to the TableWizard of RadEditor. This has been added to our TODO list for the Q1 2009 release of RadEditor for MOSS. The release will appear shortly within (a week or so) after Q1 2009 is launced.
Based on feedback, our plans were (and still are) to provide the stable styling feature into the RadEditor's own TableWizard dialog for Q1. Unfortunately, there will not be enough time to do it. We were able, however, to do a full re-work of the TableLayout engine that is now able to handle much more complex scenarios of "building" tables dynamically. Also the StyleBuilder dialog can now be called from the TableWizard. So, active work on this dialog continues and not after long you will see the missing features integrated.
All the best,
the Telerik team
