that page looks fine to me, each cell has a white border. But the boss and everyone in his office sees it as the attached. I am using: Firefox 40.0.2. They are using:
Person 1: Firefox 40.0.2
Person 2: 38.0.1
Person 3: 39
When I look at it in firebug, the CSS says the white border is there. Any ideas as to what is going on? Thanks.
We all see the same thing with the missing vertical and horizontal lines.
