Hello Pascal.

Yes, we've added some custom CSS to that page:

.wpdt-c .wpDataTablesWrapper table.wpDataTable .even:hover > td
{
    background-color: #fff !important;
}
.wpdt-c .wpDataTablesWrapper table.wpDataTable .odd:hover > td{
    background-color: #fff !important;
}
@media screen and (min-width:1024px) and (max-width:1270px) {
    td.column-os,td.column-battery,td.column-price,td.column-weight,td.column-graphics,td.column-ram,
    th.column-os,th.column-battery,th.column-price,th.column-weight,th.column-graphics,th.column-ram{display:none;}
}
@media screen and (min-width:1270px) and (max-width:1560px) {
    td.column-os,td.column-display,td.column-battery,td.column-weight,td.column-ram,td.column-graphics,td.column-processor,td.column-harddisk,
    th.column-os,th.column-display,th.column-battery,th.column-weight,th.column-ram,th.column-graphics,th.column-processor,th.column-harddisk{display:none;}
}
@media screen and (min-width:1560px) and (max-width:1700px) {
    td.column-os,td.column-weight,td.column-graphics,th.column-os,th.column-weight,th.column-graphics{display:none;}
}

Also, the background color of the header, and it's borders have been changed to white with this CSS:

.wpdt-c.wpDataTablesWrapper table.wpdtSimpleTable thead th,
 .wpdt-c .wpDataTablesWrapper table.wpDataTable thead th,
 .wpdt-c .wpDataTablesWrapper table.wpDataTable thead th.sorting {
    border-color: #f2f2f2 !important;
}
.wpdt-c.wpDataTablesWrapper table.wpdtSimpleTable.bt[data-has-header='1'] td.wpdt-header-classes,
 .wpdt-c.wpDataTablesWrapper table.wpdtSimpleTable thead th,
 .wpdt-c .wpDataTablesWrapper table.wpDataTable thead th,
 .wpdt-c .wpDataTablesWrapper table.wpDataTable thead th.sorting {
    background-color: rgb(255,255,255) !important;

You're welcome, Pascal
