table th { color: #999;
}

table .name {

}

table tr { background: #e6e6e6;
}

table tr.alt { background: #f1f1f1;
}

table td a { display: block; font-weight: bold;
}

Things to remember:

Collapse the table using <table cellspacing="0"> (or the border-collapse property), and move all other borders, background, and spacing to the style sheet.

Use the <caption> element to properly assign a title to the table.

Use <th> elements to properly denote the table's headers, thus providing better structure and a way to uniquely style those cells with CSS.

Create grid lines by adding borders to the <th> and/or <td> elements.

Add background colors to rows by styling the <tr> elements. Alternate background row colors by adding a class to the desired <tr>.
