I don't know if it is what you are envisioning, but there is a spreadsheet program called Scheme In A Grid (Siag) [1] (part of Siag Office [2]). From the "Introduction" [3] of its Online Documentation: "Siag is an X-based spreadsheet for Unix. It uses Scheme (a Lisp dialect) both for expressions and as an extension language, which makes it easy to create new functions (for native Lispers, that is). There is no requirement to know Scheme to use Siag, expressions can be entered in traditional spreadsheet syntax as well."
