I've never used DWZone's DataGrid but you should try DataTables for this - it's so simple to implement and provides a basic realtime pagination, search and filter facility without having to do anything else. It's also free! You just include a few lines of code at the top of the page, give your table an ID, thead and tbody region and that's it.
It has a massive amount of add-ons and extras too if you want to do something more complicated, although I'm not an expert on that - their forum is really helpful though. https://datatables.net/
