How can I style headers in a grid to be in Arial, 20pt?
g = Plot[x^2, {x, 0, 2}];
headers={"A", "B", "C"};
Grid[Prepend[{{g, g, g}}, headers]]
(I decided to post this question/answer because I keep stumbling onto this. I know the answer is somewhere in some question but always have a hard time finding the related question)
