It depends on when you're talking about. Obviously, before displaying the
table, you're creating the list that feeds the table, so you've got access
to that data there.
But since you mention "currently selected" rows, I'm assuming you're
referring to the user posting the table back as a form.
In that case, you'd just wrap the table in a form:
<form action="...">
<display:table blah>
<display:column/>
</display:table>
<input type="submit"/>
</form>
Whether you use <form>, <html:form>, or whatever else depends on your
framework. Once the form is posted back to your servlet, you then just
read in the parameters from the request as you normally would.
The big question comes down to what you name your parameters and how
you'll handle that. This usually happens in the <display:column> tag,
where you can do something like this:
<display:table name="listname" id="item">
<display:column title="Select">
<input type="checkbox" name="select<c:out value="${item.id}"/>"/>
</display:column>
</display:table>
Then, when the user clicks the submit button, what you'll get is a number
of request parameters named selectXXX, where XXX is whatever format your
ID is.
DON'T ask about how to preserve these selections across pages! You
shouldn't do that (IMHO, of course):

Does that answer your question?
