You can probably try and write an activity that will count the rows and will store the content in another column of the same source and then maybe you can use a repeating dynamic layout to show the values.

see attached a simple example that also uses media query to change the number of columns depending on the width of the browser - this approach can be done in Pega using an RDL - The channels and interface landing page uses a similar approach to render the different cards.
