Demo Droptables plugin to try out

Hi,

I'm looking for a Joomla table plugin which will have sortable table rows. It needs to be managed easily by boardmembers at the front end. I need a plugin like this to show the results of contests.

Before I'll get a green light for purchasing this plugin, I need to be absolutely sure this plugin meets our requirements. Is it possible to have acces to a backend demo or a free version with a limited time (a few days is enough) to test.

Thank you in advance.
