Very interesting table. As it happens the only aircraft quoted in that list that I was reasonably familiar with so far as the aerofoil is concerned is the PA-44 Seminole.
The table quotes the Seminole as having the same aerofoil at the root and tip.
The one I used to fly had a section at the root that was clearly very convex on the underside, much more flat bottomed over the middle of the wing and was concave at the tip, including a slight built in LE droop for the last few feet. I remember all this 'cos we tufted the wing and used it to teach some aspects of stalling to aero eng students. Indeed I used to talk up the wing as an example of how you could combine good natural buffet warning (from the root section which exhibited reverse flow on the upper surface when approaching the stall) good general CL max from the main wing and excellent roll control during and after the stall thanks to the LE droop in front of the ailerons.
