Table table = new Table("table"); table.setClass("isi"); Column idColumn = new Column("purchaseId", "ID"); idColumn.setFormat("{0,number,#,###}"); table.addColumn(idColumn); Column priceColumn = new Column("purchasePrice", "Price"); priceColumn.setFormat("{0,number,currency}"); priceColumn.setTextAlign("right"); table.addColumn(priceColumn); Column dateColumn = new Column("purchaseDate", "Date"); dateColumn.setFormat("{0,date,dd MMM yyyy}"); table.addColumn(dateColumn); Column orderIdColumn = new Column("order.id", "Order ID"); table.addColumn(orderIdColumn);
Column column = new Column("email"); column.setDecorator(new Decorator() { public String render(Object row, Context context) { Person person = (Person) row; String email = person.getEmail(); String fullName = person.getFullName(); return "<a href='mailto:" + email + "'>" + fullName + "</a>"; } }); table.addColumn(column);The Context parameter of the decorator render() method enables you to render controls to provide additional functionality. For example:
public class CustomerList extends BorderedPage { private Table table = new Table("table"); private ActionLink viewLink = new ActionLink("view"); public CustomerList() { viewLink.setListener(this, "onViewClick"); viewLink.setLabel("View"); viewLink.setAttribute("title", "View customer details"); table.addControl(viewLink); table.addColumn(new Column("id")); table.addColumn(new Column("name")); table.addColumn(new Column("category")); Column column = new Column("Action"); column.setDecorator(new Decorator() { public String render(Object row, Context context) { Customer customer = (Customer) row; viewLink.setValue("" + customer.getId()); return viewLink.toString(); } }); table.addColumn(column); addControl(table); } public boolean onViewClick() { String path = getContext().getPagePath(Logout.class); setRedirect(path + "?id=" + viewLink.getValue()); return true; } }
getName() + ".headerTitle"If not found then the message will be looked up in the /click-control.properties file using the same key. If a value still cannot be found then the Column name will be converted into a header title using the method: {@link ClickUtils#toLabel(String)}. @see Decorator @see Table
