fabrizio giustina closed DISPL-85:
----------------------------------
Resolution: Won't Fix
Fix Version: 1.1
the same result can be achieved without additions/modifications to the tag
library, by simply using custom beans/maps and jstl code.
An example has been added to the example webapp (see the Dynamic Column
Creation example).
This is a simple example, assuming "collist" is a list of javabeans/maps
available in the request scope.
<display:table name="test">
<c:forEach var="cl" items="${collist}">
<display:column property="${cl.property}" title="${cl.title}"
sortable="${cl.sortable}" format="${cl.format}" />
</c:forEach>
</display:table>
> Dynamic Column Creation (so called Column Collection)

> I have been needing this feature since day one using displaytag: Dynamic
> Column Creation. To be simple lets just say that a 'column collection' is
> needed. A java collection, that helds 'column' objects to be able to
> configure the table on the run. There are multiple cases where you can not
> know the number of you columns before the execution of the JSP. For example
> when you first choose which information you are interested to see in some
> report, and then other info should be omited.
