I was surprised because you didn't know how to make it shape like Pyramid.
It's not hard; you only need to create one loop for print repeated tabs.
For example: I want to print 5 rows of Pascal Triangle. In this case, for the
first row I would print 5 tabs; for the second row, I will print 4 tabs.; and so on.
And each number will be 2 tabs distance from each other.
Here my output concept: (___ represent for tab)

___ ___ ___ ___ ___ 1
___ ___ ___ ___ 1__ ___ 1
___ ___ ___ 1__ ___ 2__ ___ 1
___ ___ 1__ ___ 3__ ___ 3__ ___ 1
___ 1__ ___ 4__ ___ 6__ ___ 4__ ___1
