I got this template for a table straight from design programme Artisteer

HTML:
Naam
Slogan tekst
and CSS:
table, th, td
{
font-size: 1em;
padding: 0;
border-collapse: collapse;
}
I have enclosed two screenshots - does anybody know why it;
1. Appears different in CMSMS then when I just open the script in either FF or IE?

2. In CMSMS, appears different in IE than FF?

(besides from location)
Hope someone can help me...
Regards,
Sander
