Then what it appears to be that you are actully talking about the report that is generated from the table relationships tool and not the actual tool.
The report can be manuplated to some degree, I've never attempted this myself; however, Allen Browne has done some of this so you should read thru this material and the accompaning code/project:
Allen Browne: Relationship Report with extended field information
One thing of note " Stephen Lebans has a utility " mentioned in AB article has not been supported and may very well be broken for ACC2007 and beyond - USE IT AT YOUR OWN RISK.
BTW: Do see how using the proper syntax/grammer/jargon is an imparitive in dealing with programing/databases? If you had started out telling us that you were creating a report based upon the table relationships and needed some help with adding and deleting the tables shown....
