It looks like many of the features of DataTables don't work with JQuery 1.7. See this JSFiddle to switch between JQuery 1.7 and 1.8 easily. Everything works as expected in 1.8 and above but not in any previous versions. Is upgrading your version of JQuery possible?
I tested using the basic initialization.
HTML:
<table id='accessControlTable'>
<thead>
<tr>
<th>col1</th>
<th>col2</th>
<th>col3</th>
</tr>
</thead>
<tbody>
<tr>
<td>1</td>
<td>2</td>
<td>3</td>
</tr>
<tr>
<td>3</td>
<td>2</td>
<td>1</td>
</tr>
<tr>
<td>4</td>
<td>5</td>
<td>6</td>
</tr>
<tr>
<td>7</td>
<td>6</td>
<td>5</td>
</tr>
</tbody>
</table>
Javascript:
$("#accessControlTable").dataTable();
