I used a php callback to include a php file.
I tried to use css to control the cellspacing(border-spacing) with no avial. No matter if I use a class or id, it will not work. The table will not have any cellspacing. Even if I just use HTML, cellspacing="10".
I also have the similar problem's with lists. I have to put style="list-style: none;" in every LI just to get it to work.
