Hi,
You can do it like this:
private private DefaultDataTable<T> dataTable;
// ...
new AbstractColumn<WeekSchema>(new Model<String>("#")) {
public void populateItem(Item<ICellPopulator<WeekSchema>> cellItem,
String componentId,
IModel<WeekSchema> rowModel) {
Item<?> item = (Item<?>) cellItem.getParent().getParent();
int index = dataTable.getCurrentPage() * dataTable.getRowsPerPage() +
item.getIndex() + 1;
cellItem.add(new Label(componentId, String.valueOf(index)));
}
}
Regards,
Erwin Bolwidt
