I'm happy to help, but need a few more details to get to the bottom of this. Are you creating tables in workspaces.acrobat.com, or have you used ExportPDF to convert a PDF file to an Excel document, and that's where you're seeing the random highlighting?
I look forward to hearing back from you.
I'm new to the forum and I think I set it up incorrectly. I am actually
working in indesign and finally discovered it was a formatting/conflict
Thanks for your time.
No worries! Glad that you figured out what was going on!
