nrow and ncol for undefined values #45

When a table does not have nrow or ncol defined I we can add a description in their docstring what they should return. nothing seems a reasonable value.

Maybe missing would be the appropriate value, since there's a length but we don't know it? FWIW, Base.isdone does that.
