Style Print Button

TerryBurns

I am new to datatables/tabletools and have a basic questions. I would like to display the buttons with text,icons and rounded corners using JQuery UI . Below is my button definition but the fninit does not turn the table tools default button into JQuery UI button. Any suggestions or hints would be helpful

{
"sButtonText":"Print",
"sExtends":"print",
"sButtonClass":"myPrintButton",
"fnInit": function(nButton, oConfig ){
console.log('intit print button')
$('.myPrintButton').button({);
}
}
