ANSWERS:


Datatable requires table HTML in proper format, using <thead> and <tbody> Also number of <th> and number of <td> in all row should match. (but colspan can be used in headers) Try this HTML -

<table class="table table-striped" id="my_incidents_details" border="1">
        <thead>
                <tr>
                         <th>Number</th>
                         <th>Short Description</th>
                         <th>Category</th>
                         <th>Sub Category</th>
                         <th>Priority</th>
                         <th>Urgency</th>
                </tr>
        </thead>
        <tbody>                     
          <tr ng-repeat="num in numbers">

                 <td>  {{num.number}} </td> 
                 <td>{{num.short_description}}</td>
                 <td>  {{num.category}} </td> 
                 <td>  {{num.subcategory}} </td> 
                 <td>  {{num.priority}} </td> 
                 <td>  {{num.urgency}} </td> 

                                             </tr>
            </tbody>                                 
</table>
