Excel - conditional formatting between columns in pivot table

Question

Hi as you can see from the attached image I have a very simple pivot table which shows for each category value per year

I want to apply conditional formatting which will compare values between columns and add up and down arrows so I have the final result something like this

where of course the first column will not have any arrows but second (2015) will have arrows depending on the simple formula value (previous column) > value (current column) => green arrow, else red

I've tried to google, there are many tutorials for conditional formatting between two columns in a non-pivot table
