Table with self-check in each cell by pressing a button

I am trying to add a rational number conversion table to a lesson and I want the table to check by the press of button at the end and the checkmark/red x pop into the actual cell that is correct or wrong. I have seen these tables before but the only ones I can find to try and copy are linked to other components on the slide as well (I only want the table and the button). Does anyone know of a similar template out there that I can copy and tweak to fit my rational number table?

I have an example on the first screen of this activity.
