<td>This function adds a <code>colgroup</code> element to the table when <a href="#widthfixed"><code>widthFixed</code></a> is <code>true</code>.
<div class="collapsible"><br>
A new <code>colgroup</code> with <code>col</code> elements is only added if:
<ul>
<li><a href="#widthfixed"><code>widthFixed</code></a> is <code>true</code>.</li>
<li>A predefined <code>colgroup</code> element does not already exist in the table *.</li>
</ul>
* <span class="label label-info">Note</span> If a <code>colgroup</code> was added by the plugin, calling this function additional times will refresh the set widths<br>
<br>
Also, the <code>col</code> elements within the <code>colgroup</code> are set with a percentage width to dynamically maintain the fixed column width ratios.<br>
<br>
Use it as follows:
<pre class="prettyprint lang-js">$.tablesorter.fixColumnWidth( table );</pre>
<ul>
<li><code>table</code> - table DOM element (or jQuery object) of table.</li>
</ul>
</div>
