Hi Len:
That's a good question.  speaking strictly as one user of one particular screen reader, Jaws For windows Version 3.2,  
in the the case of  Excel 97, 
the short answer is, no, but with advanced features which would be off topic here, I think the answer would be yes.
There is a difference between saying the cell coordinates (e.g. "A1,B1,...,A2,B2,...) and the headings, presumably always in row 1?

Another approach to making data accessible is to provide a link to the data 
in a format compatible with spreadsheets.  The user can then open the data 
in a spreadsheet and travel up, down, left, and right.

We used this approach at 

We used comma separated variables (.csv) so the file could also be read 
sensibly by a straight screenreader treating it as a text file.

Does anyone know of any setups with spreadsheets and screen readers that 
read the headings as the person travels through the rows and columns?  That 
would make this technique even more useful.
