For OData and ODataV4 adaptors, you need to add expand query to the query property (of Grid), to eager load the complex data.

import { DataManager, ODataAdaptor, Query } from '@syncfusion/ej2-data';

 let  data: DataManager = new DataManager({
       adaptor: new ODataAdaptor(),
       crossDomain: true,
       url: 'https://js.syncfusion.com/demos/ejServices/Wcf/Northwind.svc/Orders'
     });
 let query: Query = new Query().expand('Employee');

 let grid: Grid = new Grid({
    dataSource: data,
    query: query,
    columns: [
        { field: 'OrderID', headerText: 'Order ID', textAlign: 'Right', width: 100 },
        { field: 'CustomerID', headerText: 'Customer ID', width: 120 },
        { field: 'ShipCity', headerText: 'Ship City', width: 100 },
        { field: 'Employee.City', headerText: 'Employee City', width: 150 }
    ],
