Table Field Docs?

[Stephen Barncard]

Peter, I agree with you about the weirdness of the table fields. 
There seems to be 'data behind data' and it's frustrating to work 
with. One can set one cell at a time, but how do we load all the 
cells at once? Putting a tab/return delimited text string in there 
goes into another dimension.
