If you are using the DataTables plug-in for jquery you can do this:

    var tabela = $('table').DataTable();

    var linha = tabela.rows(n).nodes();
   //onde n é o index da linha que deseja selecionar.

Here's an example:

$(document).ready(function () {

    for (var i = 0; i <= 5; i++) {

        $('<tr><td>linha ' + i + '</td><td>linha ' + i + '</td></tr>').appendTo('table');

    }

    var tabela = $('table').DataTable({ "paging": false, "searching": false, "bInfo": false });

    function alterarLinha(n) {

        var linha = tabela.rows(n).nodes();

        $(linha).css('color', '#ff0000');

        $(linha).find('td:first').css({ 'background-color': '#e5e5e5' });
        $(linha).find('td:last').css({ 'background-color': '#d3f9b5' });

    }

    $('input.b').on('click', function () { alterarLinha($(this).prev('input').val()); });

});
