Background cell colour in a Pivot table with monthyear as dimension
I have a pivot table with 2 dimensions and 1 measure. One of the dimensions is monthyear and the other is Customer. Now, what I want is the cell colour to appear based on the value of the previous cell (green if higher and red if lower) . Example: If, for customer A, Dec-19 sales is 100 and Nov-19 is 90, cell colour for Dec-19 should be in green and Nov-19 in red. I have data from 2015-2019. Please help me with this.
