Remove columns from Table (but keep in tool tip)

Hi michellepace 

I'd suggest you to create a custom tooltip rather than using the one by default, and then put the Reference and Person field into the tooltip. 

here's similar post for your reference: https://community.powerbi.com/t5/Desktop/How-to-Hide-Coloum-in-Table-Visualizations-to-Make-ToolTip/td-p/798978

I'll draw it up for you if you can provide the dummy pbix.
