In the dataSource object ( which in this case is a doc subclass) I

the doc object. That object is the NSMutableDictionary Object,

So, ( and I hope this comes out)

I'm still unclear why there is a (mutable) dictionary in here at
all. There's no need to have one. The simplest design is an array of
Record_objects, the table can populate itself perfectly well from
that (provided the Record_object's properties are identified in the
table, which they surely must be).
OK...I see what you are saying. I did not know I could do it that way
ie simply add the object "Record" to the record_list. I had seen an
example from the documentation which had sued this approach, so simply
followed that example! :-)
