I am trying to apply the typography rules I read here and there on the stackexchange network (vertical rules by no means, horizontal rules are often over-used, etc), and managed to do pretty well until here. Now I have a tabular which represents the results of different tests, on different platforms. Here is what I would have done with Excel :
It's not really sexy, yet it's readable, and the vertical lines do help a lot for reading in such case. How should I proceed in LaTeX, using longtable and booktabs, so have such an easily-readable array, whilst respecting the typography rules ? If I don't print vertical and horizontal lines, it is just no readable, the eyes get lost throughout reading , especially when cells of the same color are standing next to eachother (horizontally, but in particular vertically).
So I am looking for ideas on how to make such arrays readable. I am not against the idea of throwing away cellcolors if it helps by any means.
