search and count entries in a table jquery
<p>I have the following table:</p>

<pre><code>&lt;table&gt;
    &lt;tr&gt;
        &lt;th&gt;Alarm&lt;/th&gt;
    &lt;/tr&gt;
    &lt;tr&gt;
        &lt;td&gt;OK&lt;/td&gt;
    &lt;/tr&gt;
    &lt;tr&gt;
        &lt;td&gt;Missing&lt;/td&gt;
    &lt;/tr&gt;
    &lt;tr&gt;
        &lt;td&gt;OK&lt;/td&gt;
    &lt;/tr&gt;
&lt;/table&gt;
</code></pre>

<p>I want to count the rows in this table like this<br>
OK = 2<br>
Missing = 1</p>

<p>But I have no idea how to do it with jQuery, the selector should be specified just for alarm columns because I have other columns contains ok and missing</p>

<p><strong>Note:</strong> I want to count the rows for specific column in the table just for alarms column
alaram columns contains 2 ok and 1 missing.</p>
