GWT Celltable - Add multiple anchors to a cell

I am trying to insert multiple anchors in a single celltable cell. This is how it would look like-

The cars column has multiple cars, each car link can be clicked to perform different actions.
I have extended a MultipleAnchorCell class from AbstractSafeHtmlCell like this-

	import java.util.List;
	import com.google.gwt.cell.client.AbstractSafeHtmlCell;
	import com.google.gwt.core.client.GWT;
	import com.google.gwt.dom.client.NativeEvent;
	import com.google.gwt.safehtml.client.SafeHtmlTemplates;
	import com.google.gwt.safehtml.shared.SafeHtml;
	import com.google.gwt.text.shared.SafeHtmlRenderer;
	import com.google.gwt.text.shared.SimpleSafeHtmlRenderer;
	import com.google.gwt.cell.client.ValueUpdater;
	import com.google.gwt.dom.client.Element;
	import com.google.gwt.dom.client.EventTarget;
	import com.google.gwt.safehtml.shared.SafeHtmlBuilder;
	public class MultipleAnchorCell extends AbstractSafeHtmlCell {
	interface Templates extends SafeHtmlTemplates {
	@Template(" {0} ")
	SafeHtml alink(String text);
	}
	private final List items;
	public void clear() {
	this.items.clear();
	}
	public void addLink(String newOp) {
	String item = new String(newOp);
	items.add(item);
	}
	public MultipleAnchorCell(List items) {
	super(SimpleSafeHtmlRenderer.getInstance(), "click", "keydown");
	this.items = items;
	}
	public MultipleAnchorCell(SafeHtmlRenderer renderer,
	List items) {
	super(renderer, "click", "keydown");
	this.items = items;
	}
	private static Templates templates = GWT.create(Templates.class);
	@Override
	public void onBrowserEvent(Context context, Element parent, String value,
	NativeEvent event,
	com.google.gwt.cell.client.ValueUpdater valueUpdater) {
	super.onBrowserEvent(context, parent, value, event, valueUpdater);
	// Handle the click event.
	if ("click".equals(event.getType())) {
	EventTarget eventTarget = event.getEventTarget();
	if (parent.isOrHasChild(Element.as(eventTarget))) {
	Element el = Element.as(eventTarget);
	if (el.getNodeName().equalsIgnoreCase("a")) {
	doAction(el.getAttribute("aid"), valueUpdater);
	}
	}
	}
	};
	@Override
	protected void onEnterKeyDown(Context context, Element parent,
	String value, NativeEvent event, ValueUpdater valueUpdater) {
	doAction(value, valueUpdater);
	}
	private void doAction(String value, ValueUpdater valueUpdater) {
	if (valueUpdater != null)
	valueUpdater.update(value);
	}
	@Override
	protected void render(com.google.gwt.cell.client.Cell.Context context,
	SafeHtml data, SafeHtmlBuilder sb) {
	if (data == null) {
	return;
	}
	for (String item : items) {
	sb.append(templates.alink(item));
	}
	}
	}

And then I use this cell in a celltable to create a column. My User class contains comma separated values of cars in a class variable.

	List linkNames = new ArrayList();
	final MultipleAnchorCell linksCell = new MultipleAnchorCell(linkNames);
	Column carColumn = new Column(
	linksCell) {
	@Override
	public String getValue(User object) {
	String currentVal = "";
	linksCell.clear();
	if (object.getLinksToShow() != null
	&& object.getLinksToShow().length() > 0) {
	for (String hg : object.getLinksToShow().split(",")) {
	if (hg.trim().length() > 0) {
	linksCell.addLink(hg);
	currentVal = hg;
	}
	}
	}
	return currentVal;
	}
	};
	carColumn.setFieldUpdater(new FieldUpdater() {
	@Override
	public void update(int index, User object, String value) {
	if (value != null && value.length() > 0) {
	Window.alert(value);
	}
	}
	});

I am still learning GWT and it took me a while to figure this out.

Comments/feedback is welcome.
