How do I group or reference a powerpoint table from VB

I am creating a powerpoint slide from my application.  At one point I add a table and then want to populate the cells.  I need to know how to name the table, or group it with a name so that I can select it to populate it.  My code looks something like the code below ( this was generated from a macro in powerpoint, so I just need to know how to get the name like "group 142") .

        oSlide.Shapes.AddTable(11, 5, 358, 28, 300, 500)

        oApp.ActiveWindow.Selection.SlideRange.Shapes("Group 142").Select()
        oApp.ActiveWindow.Selection.ShapeRange.GroupItems(Index:=54).TextFrame.TextRange.Characters(Start:=1, Length:=0).Select()

Thanks in advance for your help.
