Stupid CSS Bugs

[Licker4U]

Couldn't find the thread I had about CSS so I'll jump on this one. I'm using:

table { background-color:#ffffff; }
td { background-color: #e00000; }

to set some colors on a page but it affects my recip links. What can I do so the recip table links are not affected?

Also, in the following, what is the "th"?

body,td,th {
font-family: Verdana, Arial, Helvetica, sans-serif;
color: #e2e2e2;
}
