Nobody is asking for explanations here, but I probably should explain anyways.
The columns here correspond to '<', '!', '>', and everything else. The fractional parts are instructions: .1 start word .3 end word .0 continue with whatever is happening The integer parts identify the row which will be used to handle the next character (and we start at row 0 for the first character, and we are not in a word when we start). Hopefully that makes sense. For further detail, I guess you'd just run it by hand on some short examples. (That's almost how I write the things.) So, for example, in gc, if you are in a word you are also on row 1. If you encounter a < you always go to row 2 (and end any word if there was one). Meanwhile, in cg, if you are in a word (if you are dealing with text which will be part of the result), you are always on row 2 - leaving the row ends that word. It's not quite symmetrical with gc because we do not want the bounding < and > to be included in the "word"s in either implementation. So that's why in cg sometimes < sends you to row 1 (which is where the words start in cg). Anyways, it's really worth running some examples through by hand if you want to see how these things work.
