Solved... it was easy.
here's the solution, I hope that could be helpful for someone...
$('.fieldsel').click(function() {
var allVals = new Array();
$('#selectcampi :checked').each(function() {
allVals.push($(this).val());
});
var collist = '{"columns":[' + allVals.toString() + ']}';
table.setView(collist);
table.draw();
});
Bye,
Marco
