How to create a state transition table for a Mealy machine

I’m trying to design the counter shown in the diagram below with the counting sequence 123456 (i.e X1=1, X2=2, …) as a Mealy machine.

However, I’m having trouble figuring out how to create the state transition table for the machine. For context, I designed this counter as a Moore machine using 3 D flip flops, and I implemented it on a FPGA board. When I push a button on the board (Rb), the number is displayed. I guess what I’m struggling with is how the table for the Mealy machine would differ from that of the Moore machine. For example, the first two rows of my Moore table look like this:

How does the input affect the output any differently than the Moore machine? (Apologies for the long question)
