We had no reason not to include it, so PD4ML does support the feature.

So it seems to be the same problem that the first post of this topic.
My CSS definition is the following:

.ui-datatable .ui-datatable-data-empty td {
border-width: 1px;
border-style: solid;
padding:4px 10px 4px 10px;

It seems to be OK with PD4ML but it doesn’t work.
If I put the class directly in the HTML element, it works.

Do you have any idea about this issue?
