It's unclear what you're asking or which Adobe app or service this is related to.

Forms have form fields, not cells. 

Cells are commonly used in tables and spreadsheets, like Excel.

Please let us know which program you are having problems with. Someone will be along to move this post to the appropriate product forum, where you are more likely to get an answer to your question.

The Using the Community forum is for help in using the Adobe Support Community forums, not for help with specific programs. Product questions should be posted in the associated product community.
