I am familiar with latter paper as well. Table by itself hard to make sense of without balance of paper. Some of the viability of crosses between species that are not closely related may be impacted by ploidy issues. You should look at effort to make intergeneric hybrids in sunfishes. Hybrids to my eyes as photographed do not look look intermediate.
I have done some Frankenfish action, with later efforts to follow up on paper above, and got really poor hatch when going between genera. For me that was useless because adult are what I wanted to mess with. Very few of the hybrids survived into the larval stage, then you had a lot of hoppers that died as juveniles. When you have to fertilize a couple hundred thousand eggs to get 3 fish large enough to see what they look like, the effort is not worth it.
