Unable to apply a new formatter with current storage mechanism

The csv was being stored (#value) as a html table instead of a serialized php object. While this saves a small amount of display time processing it wouldnt allow me to write a new formatter because id have to hand parse through the html to get to the data.

I move the table building to the default formatter and stored the table as an array which drupal takes care of in cck storage engine as seriaized array.

The trade off is small and worthwhile and it allowed me to write a JSON formatter so i could use cool charting apis. :)
