You'll probably want to adjust the behavior, but it might get you started. The method has some limitations but can work in the right circumstances.
I grabbed that demo, and I must say, it is really nice, and very impressive. That said, with no intent to snub the obvious expertise, it is hundreds of lines of custom code, which delivers a one-off solution, which still does not really behave like a "standard" data grid. This leads me only to believe that without a built-in solution, a generically useful and practical data grid is simply beyond our current capabilities.
No offense taken; the demo was written to address a particular need and it isn't suitable for all applications. It did what I needed it to do in one of my projects.
That said, I think it is possible to write just about any type of grid in Transcript, though as you say it could be time-consuming. I've also done Excel-type interfaces, where an editable field accepts user input and then places that input into a tabbed-field table object. This solves the problem of editing "cells"; all editing is done inside the entry field. If Excel can do it, so can I, and users are generally used to this type of editing.
Single-line data tables such as iTunes uses are easy to make. Just trap the tabKey message and insert a return character if the insertion point is in the last "cell". You can sort the field by column using standard "sort" syntax ("sort field 1 by item 3 of each", etc.) You can resize columns by resetting tabstops. I do this routinely. You can even create a "header" field that allows the user to drag out the columns to the widths they want, and when they release the mouse, set your data grid to the same tabstops (there are several different ways to implement the HIG for this.) Or resize the grid dynamically during the header drag; Rev is fast enough to do it.
If neither of these types of grid are what you need, tell us what you are looking for. There is nearly always a way to script it.
Real "table objects" are on the requested feature list, and I know the team has been considering how to implement them. It is a difficult thing to create, but I believe the plan is to try to build one for a future release. Meanwhile, most of us have been scripting our own solutions for years. It can be done.
