Cell Formatting - PDF Template

How can I create a border around a cell in a PDF template? I am trying to create a bold line around the cell Services in the image below.

I am having the exact the same issue. Did you ever figure this out?

border-style: solid; border-left-width: 1pt; border-bottom-width: 1pt; border-right-width: 1pt; padding: 1.45pt;

Much appreciated. Thank you!
