DataTable Fixed Header Not Being Applied
<p>I have a table using <a href="https://datatables.net/extensions/fixedheader/examples/options/header_footer.html" rel="nofollow noreferrer">datatables</a> plug-in. 
I'm trying to make my table header fixed, and follow this link : <a href="https://datatables.net/extensions/fixedheader/examples/options/header_footer.html" rel="nofollow noreferrer">here</a></p>

<pre><code>$('.device-table').DataTable( {
    "fixedHeader": {
        header: true,
    },
    "bLengthChange": false,
    "Filter": false,
    "Info": false,
} );
</code></pre>

<p>I don't see the effect. I've included both js files of datatables and fixedHeader:</p>

<pre><code>&lt;script src="https://cdn.datatables.net/1.10.12/js/jquery.dataTables.min.js"&gt;&lt;/script&gt;
&lt;script src="https://cdn.datatables.net/fixedheader/3.1.2/js/dataTables.fixedHeader.min.js" type="text/javascript"&gt;&lt;/script&gt;
</code></pre>

<p>How would one go about and debug this?</p>
