Hello cimeiformularios,

Thanks for reaching out to Jotform Support. Unfortunately, our Spanish Support agents are busy helping other Jotform users at the moment. I'll try to help you in English using Google Translate, but you can reply in whichever language you feel comfortable using. Or, if you'd rather have support in Spanish, let us know and we can have them do that. But, keep in mind that you'd have to wait until they're available again.

Now, let me help you with your question. To clarify your question, you would like to show the Table Borders on the Paragraph field, is that right? If so, here's the screencast on how to show the Table Borders:

If this is not exactly what you're looking for, please let us know.
