Initializing TableTools takes off Bootstrap classes

Sotir

var table = $('#reports_table').dataTable({
"dom": 'T<"clear">lfrtip',
"tableTools": {
"sSwfPath": "@Url.Content("~/Content/img/swf/copy_csv_xls_pdf.swf")"
}
});

With this I lose Bootstrap styles. If I remove dom + tableTools Bootstrap is normally initialized.

What am I missing?
