title: Custom gxt Cell which may take Widget
body: <p>I need a Column in which it was possible to put a Widget.
  I have this:</p>
  
  <pre><code>import com.google.gwt.cell.client.AbstractCell;
  import com.google.gwt.safehtml.shared.SafeHtmlBuilder;
  import com.google.gwt.user.client.ui.Widget;
  
  public class WidgetGridCell extends AbstractCell&lt;Widget&gt; {
  
      Widget widget;
  
      public WidgetGridCell(Widget widget) {
          this.widget = widget;
      }
  
      @Override
      public void render(Context paramContext,
              Widget param, SafeHtmlBuilder pb) {
  
      }
  }
  </code></pre>
  
  <p>But I do not know how to include the widget in HTML</p>
  
  <p>P.S. Or not Widget, only GWT Button will suit me.</p>
