<h1>Colgroup col widths</h1>
<ol>
  <li>colgroup's purpose is to "group" cols</li>
  <li>one can think of colgroup as always generating max(colgroup.span,1) cols, unless it has &lt;col&gt; children.</li>
  <li>colgroup css_width specifies width of generated cols.</li>
  <li>col.css_width can override colgroup width</li>
