In the HTML I see no any element of class ui-datatable-data-empty, so the selector always returns nothing.

If your concern is about borders of empty cells, it can be solved with

TABLE { empty-cells: show }

I made a mistake. The CSS part is the following:
[language=css:2u9e9msa].ui-datatable .ui-datatable-data td, .ui-datatable .ui-datatable-data-empty td{
border-color:inherit;
border-style:solid;
border-width:1px;
padding: 4px 10px;
}[/language:2u9e9msa]
With this one, it should work.
