Hi Bruce, This is certainly an underdeveloped class in Sage. My understanding is that the implementation is primarily designed to compute (co)spin polynomials. However, there is documentation that probably should be added to the parent class. In particular, the 0's are all values that are uniquely determined by the values and positions of the non-0 entries and k-ribbon semistandardness, which is mentioned in the RibbonTableau doc (albeit a bit too briefly). +1 for adding more functionality, but it does need someone to add it.
