repeat row button
 

Is there a code or something i can use so that for example i need to
replicate a row, or maybe two rows ( 2 and 3)(they'll be next to each other)
and replicate it directly below it, so for example i could have a formula in
a row, that i want to replicate below it so i can use it to get a different
outcome., but i want to do it by clicking a button, not using the little box
plus sign thingy. also of course it needs to replicate the button with the
row as well so i can do it again and agin.. thanks for your help!! thank you¬!
