Body:
The problem is that there are reasons to use the column body instead of coding
it into the decorator. Take for example the famous link example.
Now if I want to create a struts link for the column using a forward
(<html:link forward="...>) where a property of the decorator (e.g. "name" which
is not present in the original bean) is required, then I cannot easily do this
in the decorator. However if the decorator is exposed then this is rather easy
in the column body:
<jsp:useBean name="props" class="java.util.HashMap"/>
<!-- Init link parameter map with common parameters: -->
...
<display table id="row" name="mylist" decorator="bar.FooDecorator>
<display:column title="name" >
<!-- Add current name to the link parameters -->
<c:set target="props" property="name" value="${row.name}"/>
<html:link forward="/showFoo" name="props"/>
</display:column>
</display:table>

Description:
When doing something along the lines of:
<display table id="row" name="mylist" decorator="bar.FooDecorator>
<display:column title="name" >
<c:out value="${row.name}"/>
</display:column>
</display:table>
then the implicit 'row'-object used in the JSTL tag is not the FooDecorator
instance but the object from the list.
