Data Table from a custom list


On Apps I use a custom list to display a list of products with some additional information.
I used custom list to allow the user to select the products he is interested in.
I have for the moment put a switch but I can modify by a checkbox if needed.
I would like to create a datatable from this custom list containing the boolean (checkbox or switch). I put you a screenshot to clarify my question.

I don’t know how to do it.
I can’t create a new entity because I can have 150 users simultaneously, so it would probably be complicated to have 150 different entities. What do you think about it?
Thanks in advance for your help.
