I want to create an HTML table in which I am able to cross out cells as shown in the following drawing:
I originally thought about doing a CSS right triangle in the cell, but I couldn't figure out how to color just the hypotenuse and not the other two sides or the triangle itself.
In other words, is what I want to do possible?
Would making an image with a diagonal line and then making that image stretch 100% the width and height of the cell make the most sense?
Thanks.
