That’s a broad question. Start with a Google Search, using System.DataTable plus your required operation (DataTable alone comes up with DataTables.net, a JS-driven table for web applications such as ASP.NET MVC - so, use System. to avoid that confusion).
Sorting can be done with a standard activity. Alternatively, you can use the Invoke Code activity with anything you can find with regard to DataTables, for example (this is C#, but the object and method names are the same):
With regard to duplication handling, consider searching this forum. This question was asked (and answered!) plenty of times.
