Dear Word VBA users

I am writing on a rather long Word document (150+ pages) containing a hugh amount of Tables each containing one cell only. My job is to edit the tables: Typically changing the outline width (eventually changing to no outline) and the fill color. All of them should be handled in the same way. I don't want to do it manually, because it is a huge job. I wonder if it can be done using some VBA code automatically?

Earlier I had some experience with VBA code in Excel, but I am rather rusty on this topic. Beside I have never before used VBA code for MS Word. Hope someone can point me in the right direction.

Regards,

Erik
