Do you replace the table or only its inner html? In general, to keep the scroll position of an element, you must replace its contents (and not the element itself).
Perhaps in case of a table, you may only re-render the <tbody>, and then also only replacing its inner html.

You want to replace the row where the user clicked in, right?
The $(this) will refer to the checkbox element you clicked, but not anymore in the response script. So, you need to capture it in a lexical scope.

This is what I would try:

 onClick:  (((JSStream on: 'var myself = this'),
 		(html jQuery ajax
                          serializeThisWithHidden;
                          script: [ :s | s << (((s jQuery expression:(JSStream on: 'myself')) closest: 'tr') html: self report) ])) asFunction apply: #());

The idea is to generate this:

onclick = "(function(){ var myself = this; <<ajax call>> })()"

The above might or might not work because I did not try it. But something along those lines should work...
