Contribution: FlexTable with Model support

Hi guys,

Recently I stumbled upon the high-performance CellTable. In particular, I like its model-based approach compared to FlexTable's or Grid's 't.setText(x,y,content)'. In my case, I don't care about performance (internal app) and I'd rather like to use all the Widget goodness that I'm used to. So, as a result, I added model support to FlexTable which then allows me to do the following:

ModelFlexTable<Model> table = new ModelFlexTable<Model>();

table.addColumn(new FlexColumn<Model>() {
    @Override
    public Widget createWidget(Model row) {
        return new Label(row.getName());
    }
}, "Name");

table.addColumn(new FlexColumn<Model>() {
    @Override
    public Widget createWidget(Model row) {
        return new InlineHTML("<div style='background-color:"
                + row.getColor() + "; width:50px;height:50px'></div>");
    }
}, "Color");

table.addColumn(new FlexColumn<Model>() {
    @Override
    public Widget createWidget(final Model row) {
        Button remove = new Button("Remove");
        remove.addClickHandler(new ClickHandler() {
            @Override
            public void onClick(ClickEvent event) {
                table.removeRow(row);
            }
        });
        return remove;
    }
});

table.addRow(new Model("red", "#ff0000"));
table.addRow(new Model("green", "#00ff00"));

where the Model class is:

public class Model {
    private final String name;
    private final String color;

    public Model(String name, String color) {
        this.name = name;
        this.color = color;
    }

    public String getName() {
        return name;
    }

    public String getColor() {
        return color;
    }
}


Maybe someone finds this useful. The downside is that the nice default styling of CellTable is missing, and other features of it like paging etc. So it's not a CellTable replacement but rather a nicer-to-use FlexTable if you have a model anyway.
