All the cues for what to do and where come from the styles given to
the different html elements forming your table, if you look at the
incubator examples (for instance, the ScrollTable one at
http://collectionofdemos.appspot.com/demo/index.html), you'll see that
you get an arrow cursor in the spots you can drag to resize columns,
and clicking the header of a column will sort it.
Again, there's much more to learn from the incubator and google's own
examples than from us users here in the forum ;)
Cheers,
Salvador
