    <p>You are doing a search with $('#settbl tr').filter(':has(:checkbox:checked)') which means that , it will return the <code>&lt;tr&gt;</code> having a check box checked. But in your code as you can see Tag02's parent <code>&lt;tr&gt;</code> doesn't even have a check box . you should put both <code>&lt;input&gt;</code> that you want to be checked inside same <code>&lt;tr&gt;</code> with check box .</p> <pre><code> &lt;tr&gt; &lt;td rowspan="2"&gt;&lt;input type="checkbox"/&gt;&lt;/td&gt; &lt;td rowspan="2"&gt;Row2&lt;/td&gt; &lt;td&gt;Tag 01&lt;/td&gt; &lt;td&gt;&lt;input type="text"/&gt;&lt;/td&gt; &lt;td&gt;Units&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;Tag 02&lt;/td&gt; &lt;td&gt;&lt;input type="text"/&gt;&lt;/td&gt; &lt;td&gt;Units&lt;/td&gt; &lt;/tr&gt; </code></pre> <p>You can try this codes.</p> <pre><code>&lt;html&gt; &lt;head&gt; &lt;script src="http://code.jquery.com/jquery-1.10.1.min.js"&gt;&lt;/script&gt; &lt;script&gt; function enableRows() { $('#settbl tr').filter(':has(:checkbox:checked)').each(function() { $(this).find('input[type=text],select').each(function() { this.disabled = false; }); }); } &lt;/script&gt; &lt;/head&gt; &lt;body&gt; &lt;table border="1" id="settbl" cellspacing="0" cellpadding="0" width="500"&gt; &lt;thead&gt; &lt;tr&gt; &lt;th&gt;&lt;/th&gt; &lt;th colspan="2"&gt;Setting&lt;/th&gt; &lt;th&gt;Value&lt;/th&gt; &lt;th&gt;Units&lt;/th&gt; &lt;th&gt;&amp;nbsp;&lt;/th&gt; &lt;/tr&gt; &lt;/thead&gt; &lt;tbody&gt; &lt;tr&gt; &lt;td&gt;&lt;input type="checkbox"/&gt;&lt;/td&gt; &lt;td colspan="2"&gt;Row1&lt;/td&gt; &lt;td&gt;&lt;input type="text" disabled /&gt;&lt;/td&gt; &lt;td&gt;Units&lt;/td&gt; &lt;td rowspan="10"&gt;&lt;button&gt;Edit&lt;/button&gt;&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td &gt;&lt;input type="checkbox"/&gt;&lt;/td&gt; &lt;td &gt; &lt;table&gt; &lt;tr&gt; &lt;td&gt; Row2 &lt;/td&gt; &lt;tr&gt; &lt;/tr&gt; &lt;td&gt; Row2 &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; &lt;/td&gt; &lt;td&gt; &lt;table&gt; &lt;tr&gt; &lt;td&gt; Tag 01 &lt;/td&gt; &lt;tr&gt; &lt;/tr&gt; &lt;td&gt; Tag 02 &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; &lt;/td&gt; &lt;td&gt; &lt;table&gt; &lt;tr&gt; &lt;td&gt; &lt;input type="text" disabled /&gt;&lt;/td&gt; &lt;/td&gt; &lt;tr&gt; &lt;/tr&gt; &lt;td&gt; &lt;input type="text" disabled /&gt;&lt;/td&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; &lt;/td&gt; &lt;td&gt; &lt;table &gt; &lt;tr&gt; &lt;td&gt; &lt;td&gt;Units&lt;/td&gt; &lt;/td&gt; &lt;tr&gt; &lt;/tr&gt; &lt;td&gt; &lt;td&gt;Units&lt;/td&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; &lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;&lt;input type="checkbox"/&gt;&lt;/td&gt; &lt;td colspan="2"&gt;Row3&lt;/td&gt; &lt;td&gt;&lt;input type="text" disabled /&gt;&lt;/td&gt; &lt;td&gt;Units&lt;/td&gt; &lt;/tr&gt; &lt;/tbody&gt; &lt;/table&gt; &lt;button onclick="enableRows();"&gt;Enable Rows&lt;/button&gt; &lt;/body&gt; &lt;/html&gt; </code></pre>

Querying!

 
Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
