Hi RFoley03,
the equity table can be used to get an overview of the equity distribution hand-wise (as opposed to the equity distribution tab, where you can see it for all hands but as a graph and not for each hand pointed out). For example, an equity of 50% of range1 vs. range2 might result because each hand of range1 has 50% equity or it may emerge because range1 has some hands with 20% equity and others with 80% equity.
One conclusion is that it shows the variance of your equity. Another is that you can see the variance of villain's equity, if you only have one hand and villain has a range. If the variance of villain's range is quite high, then hand reading errors are more of a problem: If one part of villain's range is actually more present (e.g. the hands with 20% equity) than another part (e.g. the hands with 80% equity) than in your estimate, the total equity changes a lot.
If all of the hands have about 50% equity, then some more or fewer hands do not count that much.
There are other and deeper interpretations that can be used with this matrix. For example, sthief09 on deucescracked has some videos for that idea. When you create ranges against villain's ranges, you should view this matrix and think if your constellation serves your overall plan with that range.
Those are only ideas. I am no poker coach but work for PokerRanger. I know from many users that they use this tab and get great results and improvements in their game. Details about that should be found in videos, can be found out via coachings or are up to your own creativity.
Hopefully, I could help you with that. If you have other questions, please feel free to ask them!
Have a nice day,
