Thank you for contacting Syncfusion support.
We have checked your query with DataGrid in Xamarin.Forms, as you mentioned we cannot set the List<List<string>> property ItemSource of the DataGrid. In SfDataGrid DataSource is an object which supports data sources such as list, ObservableCollection. While we bind the List<List<string>> column generate with properties of list, so that we cannot List<List<string>> type to ItemSource. We have prepared the sample based on your requirement and attached the sample for your reference.
