Hi Nauseous_p and welcome to our forum!
The most common solution is to some code to insert the rows. There may be a non-code solution - you can add several hundred default rows (blank) to your sample data (Tools->Sample Data) and use a condition defined on each row that uses xpath position() function to conditionally hide individual rows based on number present in another field. I.e. if (my:count < position()) then hide display. Good luck!
