You don't need the <c:forEach/> tag. The displaytag iterates the list for you.
So....
<display:table name="tabEnv" id="row">
<display:column title="Id">
${row.id}
</display:column>
<display:column title="Name" property="name"/> <%-- alternate way to access a
list element property --%>
</display:table>

There are two displaytag jar files that start: "displaytag" and
"displaytag-el". If you are using Tomcat 5 or 6 you only need the
"displaytag" version as the expression language is built into Tomcat. If
you were using Tomcat 4 you would need to use "displaytag-el" if you
wanted to use expression language in your displaytag tags.
