Answer 2

this is the solution if you need to add clickableTextCell to cellTable
// ClickableTextCell
ClickableTextCell anchorcolumn = new ClickableTextCell();
table.addColumn(addColumn(anchorcolumn, new GetValue<String>() {
public String getValue(Contact contact) {
return "Click " + contact.anchor;
}
}, new FieldUpdater<Contact, String>() {
public void update(int index, Contact object, String value) {
Window.alert("You clicked " + object.name);
}
}), "Anchor");
private <C> Column<Contact, C> addColumn(Cell<C> cell,final GetValue<C> getter,
FieldUpdater<Contact, C> fieldUpdater) {
Column<Contact, C> column = new Column<Contact, C>(cell) {
#Override
public C getValue(Contact object) {
return getter.getValue(object);
}
};
column.setFieldUpdater(fieldUpdater);
return column;
}
private static interface GetValue<C> {
C getValue(Contact contact);
}
// A simple data type that represents a contact.
private static class Contact {
private final String address;
private final String name;
private final String anchor;
public Contact(String name, String address, String anchor) {
this.name = name;
this.address = address;
this.anchor = anchor;
}
}

Create a Column overriding the onBrowserEvent method.
Like this:
new Column<T, String>(new TextCell()) {
#Override
public String getValue(T object) {
return object.getProperty();
}
#Override
public void onBrowserEvent(Context context, Element elem, T object, NativeEvent event) {
// TODO You can check which event you want to catch
Window.open("http://www.stackoverflow.com", "StackOverFlow", "");
}
};
