How do I customise the background-color of the DataTable's selected/active row?
Inspect Elements Styles:
.ngx-datatable.material.single-selection .datatable-body-row.active, .ngx-datatable.material.single-selection .datatable-body-row.active .datatable-row-group, .ngx-datatable.material.multi-selection .datatable-body-row.active, .ngx-datatable.material.multi-selection .datatable-body-row.active .datatable-row-group, .ngx-datatable.material.multi-click-selection .datatable-body-row.active, .ngx-datatable.material.multi-click-selection .datatable-body-row.active .datatable-row-group {
background-color: #304ffe;
color: #fff;
}
