Yes, you can easily do this with javascript and WITHOUT extending the
grid by using a mixin.

First of all, if you haven't already, digest the documentation on mixins:
http://tapestry.apache.org/tapestry5/tapestry-core/guide/mixins.html

If you're clear on that, then the only piece you're missing is how to
connect JS to the grid. For that your mixin should instantiate a JS
object and be passed the client side DOM id of the grid. From there it's
in the hands of your JS code. Have a look at the Autocomplete mixin
source, or at these:

(line 67)
http://code.google.com/p/tapestry5-components/source/browse/trunk/commons/src/main/java/org/apache/tapestry/commons/components/SlideShow.java

(line 78)
http://code.google.com/p/tapestry5-components/source/browse/trunk/commons/src/main/java/org/apache/tapestry/commons/mixins/Resizable.java

The first is a component, the other is a mixin. This doesn't matter as
the process for connecting JS to the generated element is the same. See
those indicated lines? That's the glue. Study that for a bit and see if
you can make some progress.
