Background transparent will not provide perfect view of that dataTable because first 2 columns are fixed.
Use below custom css to make all backgrounds black (it will not effect any other table):-
div[id*="ccpw-datatable"].dataTables_wrapper .table-striped>tbody>tr:nth-of-type(odd),
#ccpw-coinslist_wrapper .table-striped>tbody>tr:nth-of-type(odd) td:nth-of-type(1),
#ccpw-coinslist_wrapper .table-striped>tbody>tr:nth-of-type(odd) td:nth-of-type(2),
#ccpw-historical_tbl_wrapper .table-striped>tbody>tr:nth-of-type(odd) td:nth-of-type(1) {
background-color: #232323 !IMPORTANT;
}
div[id*="ccpw-datatable"].dataTables_wrapper .table-striped>tbody>tr:nth-of-type(even),
