Conditional formatting: Showing direction arrows for a series

Question

I'm using Excel 2010.

Does anyone have a quicker way of implementing this?:

I have a table, with 2 columns; all I want is a green arrow (upwards) or red arrow (downwards) if the value on the right is bigger/smaller than the value on the left.

Unfortunately I can only get condition formatting to work on each individual cell (so when I have 15+ rows, in theory I would have to create 15 'rules'. Is there a quicker way of creating some sort of series that can be easily replicated?

Thank you!

You can use a helper cell to with something like =IF(A1>B1,1,0) and then apply the conditional formatting for the arrows for the whole table. You might need to adjust when what arrow shows up but when I threw it in a sample sheet it worked by default. You can set it to show the icon only too.
