Hi Garth,
Yes, you are absolutely correct, Word is being “smart” when opening the file. The issue is that the actual layout of the table is sometimes just a set of desired configurations, and Word will do whatever it wants to.
The genesis of this issue is that it is quite possible to set up a table with invalid column widths with regards to content, and Word then does whatever it wants with the table.
I have seen this, but it has never become important to me to fully understand the algorithm that Word uses. Further, I think it likely that different versions of Word behave differently, but I don’t know.
Best, Eric
