Well. English is not my main language. But i'll try to explain. I performed a two step process. First step (the one i posted earlier) is just using built-in sort function. This function only works one dimensional. So you need a loop for every row (or column if you prefer). Sort function only work from small to large. So an extra reverse is needed. Second step is shifting. With a help of a loop, first i found empty rows (i named it starting row). And with another loop i found filled rows (i named it target row). I copied target row to starting row. And then i give 0 to target row
