CSS table cellpadding and cellspacing?

table {  
    border-collapse: collapse;
}
th, td {
    padding: 0;
}

The accepted answer of border-collapse:collapse; is not the right way to get rid of cellspacing. It works for simple solid border styles, but it is easily seen to be wrong if td{border} is set to something complicated, like inset or outset. The right answer is border-spacing:0;
