No, I understand the limitations of the Report Links, I'm just wondering what you're wanting to do with the data in the Rich Text Formula? Are you wanting to display those records in a table that's styled in a way of your selection or are you wanting to capture/display data that could be accessed using Summary functions or other native functions?
I'm assuming you're wanting to style the table and if so, you're right about needing to use JS to query the child records. This would require either injecting JS into the form to display your HTML immediately on opening the record OR require the user to click a button to load JS from a Code Page. The first option is what most people have used in the past and presents a possible security issue. Because of this, Quick Base will be limiting this option in the near future, so I would not recommend this option.
With the improvements to formulas coming, it might be best to deal with the standard styling until these new options are available.
