Datatables - How do I change background and text color of a cell changed dynamically?

I use the following code to update a cell dynamically and works perfect, the only thing is how to change the color of the background and the text of that cell data. If it´s possible an example of how to change the entire row as well. Thanks in advance.

$(document).ready(function (){
    var table = $('#example').DataTable();

    table.rows().every( function ( rowIdx, tableLoop, rowLoop ) {
        var data = this.data();       
        console.log(data);

        data[0] = '* ' + data[0];

        this.data(data);
    });
});

SOLUTION

You can access the cell node by using cell().node() API method.

$(document).ready(function (){
    var table = $('#example').DataTable();

    table.rows().every( function ( rowIdx, tableLoop, rowLoop ) {
        var cell = table.cell({ row: rowIdx, column: 0 }).node();
        $(cell).addClass('warning');
    });
});
