Tables: Preserve formatting from MacOS to Windows

As a cross-platform user, I would like to retain table formatting when opening the same project in either MacOS or Windows.

Not meaning to request identical table creation/formatting functionality in each version! Would just ask that the Windows version not clobber existing table formatting (specifically borders and column widths) set in MacOS.

(Would not be surprised if this change would take roughly the same amount of work as feature parity would be. If that’s the case, please disregard. Thank you!)
