TableTools example - multi-row select is not working

ssathiz

I have followed the example from this link: http://datatables.net/release-datatables/extras/TableTools/select_multi.html

This is my init code:
$(document).ready( function () {
$('#companies').dataTable( {
"sDom": 'T<"clear">lfrtip',
"oTableTools": {
"sRowSelect": "multi",
"aButtons": [ "select_all", "select_none" ]
}
} );

This is my body code:







Company name
Address
Town




ABC
ABC Street
Town1


Dell
Car street
Town2









I don't know, what is wrong here. I'm not getting the 'select all', 'deselect all' buttons and single row select also. I'm new to datatables. Kindly help me.
