It does, see:

Possibly.  You might also want to consider noweb syntax or named results.

You already get the table as a list of lists structure when referenced 
as a variable in the call, see above.  The variable indexing might 
reasonably be extended to extract named rows and columns so that the 
helper function would not be needed and something like 
cname=card-table["cname",] would be possible, I'd think.
