These examples might help...
If you’re not using AJAX then it probably makes more sense to put the Form
around the Loop:
T5.4:

<http://jumpstart.doublenegative.com.au/jumpstart7/examples/tables/editableloop1>
http://jumpstart.doublenegative.com.au/jumpstart7/examples/tables/editableloopforupdate1
<http://jumpstart.doublenegative.com.au/jumpstart7/examples/tables/editableloopforupdate1>
T5.3:

If you’re using AJAX, then a Form per row works well:
