If you have a complete list of all the unique names allowable (not hard to 
do, if they're really the months :-), you can create a lookup table for 
reference. In this case, a simple list of the months will do. Iterate over 
the lookup table (it can be in your stylesheet, accessed as a node set with 
the document('') trick) and generate one <td> for each. If in the row you 
are working on, that month has an entry, populate it accordingly; otherwise 
just put a non-breaking space in there.

If the allowed values are not all known in advance, a two-pass solution, or 
a node-set extension function, can allow construction of this lookup table 
dynamically.

Sorry I can't show this in code! at the moment ...but "lookup table" in the 
FAQ should turn up something about this technique.

Cheers,
Wendell
