i have a really nice style for my tables.
{ sorry links no more working }
I had to add sClass so that new rows (added by fnAddData) get the right classe
let table = $("#myTable").dataTable();
table.rows().every(function(rowIdx, tableLoop, rowLoop){
$(this.node().cells[0]).addClass('red');
$(this.node().cells[1]).addClass('blue');
}
After the table is rendered, iterate through all rows with the JavaScript selector of each row and make whatever changes you want. This addresses the performance concerns brought up by gamliela in loostr's answer. DataTables rows().every() documentation
