Expected behavior If I am creating a datatable using a div with the class datatable around HTML, I would expect that custom data- attributes defined in the cells to be present in the final rendering. For example:

<!-- In my HTML file-->
<td data-my-custom-prop="42" ><small>Cell content</small></td>
...
<!-- when inspecting the element on the rendered page -->
<td [...styles from formatCell] data-mdb-field="field_3" false="" data-my-custom-prop="42">
            <small>Cell content</small>
 </td>

Actual behavior

 <!-- In my HTML file-->
<td data-my-custom-prop="42" ><small>Cell content</small></td>
...
<!-- when inspecting the element on the rendered page -->
<td [...styles from formatCell] data-mdb-field="field_3" false="">
            <small>Cell content</small>
 </td>

I.e. the custom prop is not carried into the rendered datatable
