How can I make the redactor table plugin show extened options? When I use the Redactor table plugin everything works but I can't seem to get any extended functions to work like cellpadding, cellspacing, table border color etc.

How do I do that?
I don't think the features you're asking for are possible with the default Redactor Table plugin Craft comes with, and as far as I know, it is also the only table plugin for Redactor out there.
