Grid / Multi-column headers

The Telerik for ASP.NET Core DataGrid supports multi-column headers by specifying column groups which incorporate inner-column structures.

In this demo, you can see the Contact Info and Location columns have nested columns, defined trough the Column Builder:

columns.Group(group => group.Title"Contact Info").Columns(col => { col.Bound(x => x.ContactTitle).Width(200);}));

In addition, operations like sorting and filtering are supported on each column level, regardless of the chosen multi-header pattern.
