Listing for Datatable rendered event

I have limited experience as a developer with the datatable and am having difficulty running a javascript function after my YAHOO.widget.DataTable is populated. My intent is to deactivate (hide) a panel that is displaying a '.gif' while the table is loading. I attempted to do something like this: myDataTable.subscribe("rendered", YAHOO.Loading.container.loading.hide()); in order to subscribe to the 'rendered' event. But I get an error message in Firebug stating 'Invalid callback for subscriber to 'rendered.' I've looked through the DataTable api but have been unable to see where the problem lies. Any suggestions?

Respectfully,
Steve
