Does anybody know a way I can insert blank lines into a pivot table or change the size of the font based on an expression

As you can see from the image below, I have been able to change to background colour and font style based on the dimension value by using expressions like =if(Total_Column> 0,'<B>' ,) , but my sponsor is being quite particular about wanting blank lines inserted after 'Net Property Income', Total amin Exes'  and ' Operating result'

He also wants to increase the font size of these lines. Can this be done?

Many thanks,

Lawrence
