How to hide the corresponding td childs in a spanned column
<p>Here the table header has both rowspan and column span. How can I hide corresponding <strong>child td's</strong> while clicking the <strong>Hide</strong> link in the header column?</p>

<pre><code>&lt;table border="1" cellspacing="1" cellpadding="1"&gt; 
&lt;tbody&gt;

<p>In case of dynamic row and column spanned headers, is it possible to reterive the corresponding td's child of header column.</p>
