Answer by Malvineous for Set cellpadding and cellspacing in CSS?

For those who want a non-zero cellspacing value, the following CSS worked for me, but I'm only able to test it in Firefox.

See the Quirksmode link posted elsewhere for compatibility details. It seems it may not work with older Internet Explorer versions.

table {
    border-collapse: separate;
    border-spacing: 2px;
}
