The Metronic Datatable component supports local or remote data source. For remote data you can specify a remote data source that returns data in JSON/JSONP format. In this example the grid fetches its data from a remote JSON file.
It also defines the schema model of the data source received from the remote data source. In addition to the visualization, the Datatable provides built-in support for operations over data such as sorting, filtering and paging
performed in user browser(frontend).
