<p class="tip">
<em>NOTE!</em>
</p>
<ul>
<li>In <span class="version">v2.15.0</span>, the <code>parsed</code> parameter
<ul>
<li>This parameter is a flag used by the filter widget.</li>
<li>When <code>true</code>, the filter widget will only search through parsed data for matches.</li>
<li>If <code>false</code> (default value), the filter widget will search through the cell text for matches.</li>
</ul>
</li>
<li>This method of writing custom parsers will NOT work with the original tablesorter 2.0.5b plugin because the format function does not consistently provide the <code>cell</code> and <code>cellIndex</code> parameters.</li>
</ul>
