$('#mainTable').dataTable({
    dom: 'T<"clear">lfrtip',
    tableTools: {
       "sSwfPath": "../swf/copy_csv_xls_pdf.swf"
    },
    "scrollY": 300,

I have made this worked before by downloading the swf object and referencing the sswfpath to that location.

    Please check the fiddle and change the "sSwfPath"
 with the location of the downloaded
 copy_csv_xls_pdf shockwave flash object.

You can download the swf file from https://github.com/DataTables/TableTools/blob/master/swf/copy_csv_xls_pdf.swf
