You will have to find some way to send information about which columns are visible to your web application when the user uses the export link. That way when you construct the <display:table> tag you can include only these columns. The export link always involves a call to your server and your server is where the export data is compiled and rendered. Your server is going to need to be told which columns the client has visible by some method.
