 Hi,

I've been noticing that new users again and again (me
too, when I started) have a question like:

http://www.mail-archive.com/displaytag-user%
40lists.sourceforge.net/msg01625.html

***
New to using the display taglib and am stumped by this
on. Is there anyway to put more
than one data column in a single table column? In my
case, I'm trying to output names.
The
names are stored as firstname, middlename, and
lastname; each individual columns in the
database table. I'd like to output them like "lastname,
firstname middlename" all in
the
same column.
***

Usually there's at least one wrong or overly complicated
answer (use a new property, use a Decorator) before
the optimal answer: use <display:column> with a body.
This tells me there's a lot of users out there who never
learned this.

I suggest an example of this be added VERY
PROMINENTLY to the website. Maybe in the tutorial
page under basic usage. (It is pretty basic - I use it all
the time).

<display:column title="name" >
<c:out value="${row.first_name}"/>
<c:out value="${row.last_name}"/>
</display:column>
