It wouldn't be an empty column it'd be a column with a link like this in it:
<a href="#" class="DATA-LINK"
onclick="javascript:populate_parent('name=Crazy;code=crazy')">Click Me</a>

Absolutely. If you're using a TableDecorator you can use a
<display:column property="madeUpValue"/> tag as long as your decorator
has a public String getMadeUpValue() method. DisplayTag will look in
your decorator for the property and only if it cannot find one there
will it go on to look for it in the data Object itself. This is useful
if you want to concatenate two of your object's fields into one table
column or carry out some other manipulation of the object's data before
display.
