The general idea is correct though.
You’d use the ${foo.id} _expression_ wherever you’d pass the
parameter to the tag that generates the link. So instead of having a
direct href, you could have:
<portlet:something action=""
param0=”${foo.id}”/>
If you don’t have the ability to use
an _expression_ in your tags or the tags don’t support parameters of any
sort, then the problem lies in the portlet tag library you’re
using. But as far as displaytag goes, that’s how you’d do it
(assuming you’re using EL; if not, you can use a scriptlet instead, but
the concept’s the same).

Using DisplayTag in Portlets
edit.html?...
Hey... I'm working inside a portlet. Not allowed to have direct links in JSP.
It's a biggest blunder that I'd ever do.

You can construct your own URL inside a table cell - just leave the
"property" element out and give the cell a body. For
example:
<display:table id="foo">
<display:column>
<a href=""
value="edit.html?id=${foo.id}"/>">Edit</a>
</display:column>
