### Why is this important?
The ARIA specification provides a set of accessibility roles as the main indicator of control's type.
These roles support platform accessibility APIs.
By assigning a valid ARIA role on an element, as defined in the ARIA specification,
assistive technologies leverage the role's semantics to provide consistent object interaction and presentation.

<div id="locSnippet"></div>
### What to do
* Remove any `role` attributes from table structure elements (`<tr>`, `<th>`, `<td>`) within any
container with a role of `"table"`, `"grid"`, or `"treegrid"`.
Code example of a table with a valid `role="grid"` and appropriate table structures:
```
<div id="caption" class="caption">Table caption</div>
<table role="grid" aria-labelledby="caption" class="gridCls">
<thead>
<tr>
<th>Head 1</th><th>Head 2</th>
</tr>
</thead>
<tbody>
<tr>
<td>Cell 1</td><td>Cell 2</td>
</tr>
</tbody>
</table>
```
