I have a standard table type that I need to use in my user documentation. It
doesn't match any of the table autoformats provided. Is there some way that I
can define my table once and then tell Word "Save this as an autoformat".
Then I can simply create the table and apply the autoformat.

Another acceptable option would be if I could right click and select some
option to save the table format as the default table format for the document
(the way you can with autoshapes). Ideally, I'd like to include table formats
within my template documents.
