Accessible web datagrid?

I'm building a budget webapp, mostly for my personal needs and for the sake of self training. I may release it later at some point.

The interface will feature a table of operations (credit / debit). I was planning to use Ajax to make the table "editable" by clicking in a cell (Excel-like). I therefore need to:

• diplay operations

• add new ones
• modify existing ones

I fail to see how to make "modify" degrade nicely, as if you remove JS, this will be a plain old table without the possibility to modify an existing entry.

Turning the table into a giant form would be ugly, adding links to edit each operation then hide them using JS seems fairly complex...

One possible solution would be to add links that go to other forms that allow the modify operations to take place. This is much less fluid than in-place edits for accounts, but it still remains accessible without being burdensome (like a huge page of form inputs would be).

You can then override the links with javascript to give the ajaxy, web-app functionality you are looking for.
