In GXT2 I used to have a ListStore of a model containing the fields "unit" and "value". Then I created a Grid using the ListStore and a ColumnModel. The ColumnModel had a ColumnConfig for the "value" field. This ColumnConfig got a Renderer for showing "unit" next to "value" in that column.

GXT 2 - Code
        List<ColumnConfig> configs = new ArrayList<ColumnConfig>();

        ColumnConfig valueColumn = new ColumnConfig("value", "value", 100);

        ColumnModel cm = new ColumnModel(configs);

        Grid<MyModel> grid = new Grid<MyModel>(ingrStore, cm);
With the unitRenderer being:
public static final GridCellRenderer<MyModel> unitRenderer = new GridCellRenderer<MyModel>() {
        public Object render(MyModel model, String property, ColumnData config, int rowIndex, int colIndex,
                ListStore<MyModel> store, Grid<MyModel> grid) {
            Double value = model.get(property);
            if (value == null) {
                return "";
            String unit = model.getUnit();
            return value.toString() + " " + unit;

Question: How to accomplish this in GXT3?

I know about setCell() and the render-Method there. But Model, Store and Grid aren't accessible over there.

What I got so far (GXT 3):
ColumnConfig<MyModel, Double> valueColumn= new ColumnConfig<MyModel, Double>(props.value(), 100, "value"); 

valueColumn.setCell(new PropertyDisplayCell<Double>(new DoublePropertyEditor(numberFormat)) {

     public void render( context, Double value, SafeHtmlBuilder sb) {

        String unit = "unit";//FIXME: How to get unit out of model here?

        sb.appendHtmlConstant("<span>" + value.toString() + " " + unit + "</span>");      }
