I didnt get the datatable format in my page
<p>I added a datatable for one page, but it shouldn't get the datatable format</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/1.10.12/js/dataTables.bootstrap.min.js"&gt;&lt;/script&gt;
&lt;table class="example3" id="example1"&gt;
    &lt;tr&gt;
        &lt;td&gt;&lt;/td&gt;
        &lt;td&gt;&lt;/td&gt;
    &lt;/tr&gt;
&lt;/table&gt;

&lt;script&gt;
  $(document).ready(function() {
    $('.example3').DataTable();
    alert('1234567890');

  } );
&lt;/script&gt;
</code></pre>

<p>I got an error like this, I checked both the class and id class 
they both come from the database. If I remove the data I also don't get the values.</p>

<p>TypeError: c is undefined     </p>

<pre><code>    ...ldren("th, td").each(function(a,b){var c=o.aoColumns[a];if(c.mData===a){var d=s(...
</code></pre>

<p>Please let me know where the mistake is, because the same code used in other projects works.</p>
