How can I put a widget in a CellTable Cell?

I am using CellTable to show my records but now the thing is I want show a select box when user clicks on a cell. One more thing is that select box is my own widget, not a predefined. Can you please suggest to me any method of doing this?

There's a post on the GWT google group that discusses the answer. Basically you create your custom widget as normal, and inside the render function you use widget.getElement().getInnterHTML().

@Override
public void render(com.google.gwt.cell.client.Cell.Context context,
            String value, SafeHtmlBuilder sb) {
        if (value != null) {
             MyWidget widget = new MyWidget(value);
             sb.appendEscaped(widget.getElement.getInnerHTML()); 
        }
}
