I haven't tried this so there may be some issues, but you might be able to use
multiple table views, each contained in a Rollup, to get this behavior.
TableView's "columnSource" property allows you to link a collection of table
views to a primary table view that defines the columns.

I am doing exactly this in an application I'm working on right now. You can
register a mouse listener on the table view header, then use the mouse
coordinates to get the index of the selected header. You can then call
getHeaderBounds(index) to get the header bounds and align your popup to it.

As Todd suggested, the best approach would probably be to use a FilteredList.
However, you might also simply resubmit your query to the server (this is what
I am doing in my app).

Again, as Todd suggested, a custom renderer is probably what you want here. I
am doing the same thing in my current app. For ListButton, you'll probably need
two custom renderers: one for the selected button data and another for the list
items. Simplest thing to do is extend the default renderers (in
org.apache.pivot.wtk.content), use JSONSerializer to extract the value you
need, then pass it to the base render() method.
