There are any way to create on Ninox a HTML report like this, there are some examples here.
I want some reports like this layout and have been badgering Ninox support for ages. to date they offered me one suggestion which did not work
As Usual with Ninox Support
I do create pretty nice looking reports in Ninox by just programming HTML layouts and saving them in a Rich Text fields. Then the program does call by API an HTML to PDF server converter and automatically import the result as a PDF report.
