Shouldn't CSS over ride tag attributes?

Friend mailed.
He told me he's done a table with a 3px wide border defined in CSS, but
the border happened to be present in the table tag too, with 2px width.
When checking in Safari, the border becomes 5px wide.
The question is not "how can I fix this" since he knows how to delete
the attribute in the tag, but he merely wondered if CSS wasn't supposed
to over-ride tag attributes and if Safari made something wrong.
To me, Safari screws up, but I wanted to have this confirmed.
Well?

The HTML attribute "border" on a table, will also affect the TD. So a
rule like this should theoretically work:

table {border: 1px solid red;}
td {border: 0;}

Ah, so Safari isn't screwing things up? The tag attribute still gives a
border to the cell (<td>) and the CSS gives border to the table itself?
OK. Thanks.

Yep. Additionally tables have a default value for cellspacing and
cellpadding. Usually a border="1" on the <table> tag will lead to a 1px
border around the table, another 1px around the cells and some space
between them.
