Process tables by number of rows, row height, and alert if no tables exist in jquery
<p>I have this code right now:</p>

<pre><code>var table = $(source).children('table').map(function() {
if (this.rows.length &gt;= 4) {
    return $(this).outerHTML();
} else {
    return null;
}
}).get();
</code></pre>

<p>This will get tables by number of rows, but how would I get the tables by row height (if height &lt; 100 px) also and also alert if no tables are in the array (if the array is empty).</p>
