    <p>I can sort a dataTable on negatives just fine, but I wanted to filter instead of sort on a select.change() event. Basically, I just need it to take the value of column 4 and render the row based on the select box selection { all, positive, or negative }.</p> <pre><code>&lt;table class="data-table"&gt; &lt;thead&gt; &lt;tr&gt; &lt;th&gt;Text&lt;/th&gt; &lt;th&gt;Text&lt;/th&gt; &lt;th&gt;Text&lt;/th&gt; &lt;th&gt;Value&lt;/th&gt; &lt;/tr&gt; &lt;/thead&gt; &lt;tbody&gt; &lt;tr&gt; &lt;td&gt;Lorem&lt;/td&gt; &lt;td&gt;Ipsum&lt;/td&gt; &lt;td&gt;Dolor&lt;/td&gt; &lt;td&gt;$1.99&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;Lorem&lt;/td&gt; &lt;td&gt;Ipsum&lt;/td&gt; &lt;td&gt;Dolor&lt;/td&gt; &lt;td&gt;$2.99&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;Lorem&lt;/td&gt; &lt;td&gt;Ipsum&lt;/td&gt; &lt;td&gt;Dolor&lt;/td&gt; &lt;td&gt;$-1.99&lt;/td&gt; &lt;tr&gt; &lt;td&gt;Lorem&lt;/td&gt; &lt;td&gt;Ipsum&lt;/td&gt; &lt;td&gt;Dolor&lt;/td&gt; &lt;td&gt;$-2.99&lt;/td&gt; &lt;/tr&gt; &lt;/tr&gt; &lt;/tbody&gt; &lt;tfoot&gt; &lt;tr&gt; &lt;td colspan="4"&gt; &lt;select class="select-filter"&gt; &lt;option value="1"&gt;All&lt;/option&gt; &lt;option value="2"&gt;Positive&lt;/option&gt; &lt;option value="3"&gt;Negative&lt;/option&gt; &lt;/select&gt; &lt;/tr&gt; &lt;/tfoot&gt; &lt;/table&gt; </code></pre> <p>Then I've tried a couple of js:</p> <pre><code>$(function(){ $(".data-table").dataTable(); $('.select-filter').change(function(){oTable.fnDraw();}); }); </code></pre> <p>But the one that "looks" easiest to make do what I want is:</p> <pre><code>$(".data-table").dataTable().columnFilter({ aoColumns: [ null, null, null, {type: "select"} ] }); </code></pre> <p>Although, that one will just create a select that contains all the values. How can I accomplish this?</p>

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.

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