How to stop row borders from overlapping table borders
I have a feeling the answer to this is "you can't", but I'll ask anyway because some of my users don't like this. Neither do I, actually, and I can't figure out why it would happen like this.
We have tables with a black border around the outside and a thin grey border separating the rows and columns. The grey row border line intersects and overlays the black table border, so it looks like a series of dashed lines (if you zoom in enough). Oddly, the column borders do not do the same thing: the table border at the top and bottom are uninterrupted. See graphics.
So why is this, and is there any way to fix it?
