How to not display a row in based on the row content?

[Paul Spencer]

I am have a list that is displayed by <t:dataTable>  I would like to 
selectively display the object in that list, i.e. filter them, via the 
JSP tag configuration.

As an example the collection contains a list of parts.  The part object 
also contains the method isInStock().  So the <t:dataTable> should only 
display object where row.isInStock() is true.

I know that a new list containing only inStock object can be created and 
that list could be passed to <t:dataTable>, but I have simplified the 
example for the purpose of this illustration.
