Can anyone point me at some examples of Groovy's closureColumn for SwingBuilder Tables?

Question

I'm working on some GUI code in Groovy using SwingBuilder.

One of the elements on the screen is a JTable that's being used, essentially, as a properties editor. Groovy in Action has a fantastic example of how to do a display-only table, with what amounts to a side note that you can also attach a write closure. GiA's example is pretty consistant with the other examples I've found on the net: lots of read-only examples, not a lot of read-write examples.

I've got, basically, this:

table() {
  tableModel( list : editorData ) {
    closureColumn(header: 'Component Attribute', read: {it.attribute} )
    closureColumn(header: 'Value', read: {it.value}, write: { ?? }   )
  }
}

In a theoretical sense, I get what needs to be in the write closure: code that fires when the user edits that cell. But examples, like I said, are hard to come by, so I'm a little shaky on how that's actually supposed to work.

Can anyone point me at an example of using something like the above?
