Fixed 'thead' width doesn't match with the 'tbody' width
<p>I have a table that has the <code>&lt;thead&gt;</code> fixed, but each <code>&lt;th&gt;</code> in it doesn't match with the width of the respective columns (<code>&lt;td&gt;</code> in the <code>&lt;tbody&gt;</code>).</p>

<p>If you need more info just ask me. Thanks in advance.</p>
