title: Multiple $expand Parameters in OData binding
body: <p>I have a table binding and consuming the publicly available OData service from the ES4 SAP system. My root entity set is <code>ProductSet</code> and it has 2 navigation properties: <code>ToSupplier</code> and <code>ToSalesOrderLineItems</code>.</p>
  
  <p>I am able to issue the <code>$expand</code> parameter in the table bindings as follows, but could you please assist me in how I can <strong>pass both navigational properties</strong> so that the OData service expands both <code>ToSupplier</code> + <code>ToSalesOrderLineItems</code>?</p>
  
  <pre class="lang-xml prettyprint-override"><code>&lt;Table items="{
    path: '/ProductSet',
    parameters: {
      expand: 'ToSupplier'
    }
  }"&gt;
  </code></pre>
