Subject [jira] Commented: (CLK-298) Tables Should Allow Adjacent Columns To Be Tied Together For Sorting
Date Wed, 03 Mar 2010 13:42:27 GMT

Joseph Schmidt commented on CLK-298:
------------------------------------

But can't be the above simply be done using a Table Decorator? Like:
http://avoka.com/click-examples/table/table-decorator.htm

but instead of having:
~~~~~~~~~~~~~~
column = new Column("date");
column.setFormat(....);
table.addColumn(column);

column = new Column("time");
column.setFormat(....);
table.addColumn(column);
~~~~~~~~~~~~~~
you would use something like:
~~~~~~~~~~~~~~
column = new Column("both");
column.setDecorator(new Decorator() {
            public String render(Object row, Context context) {
                Customer customer = (Customer) row;
                String date = customer.getDateAsString();
                String time = customer.getTimeAsString();
                return date+"|"+time;
            }
 });
table.addColumn(column);
~~~~~~~~~~~~~~

> It would be nice to be able to "tie" together adjacent column values together in a table
(e.g. date and time) for sorting purposes. Often a result set, which can otherwise be used
directly as a table model has values which should be combined for sorting purposes. Without
direct support for this in the Table class, the only way to achieve the result is defining
a view model solely for that purpose. At best this is a programming pain, and a worst unnecessarily
inefficient.
