Is there any way to do very simple spreadsheeting (rows, columns, plus, minus, multiply, divide, sum of range) like below without using monsters like Excel, Numbers and Google Spreadsheet?

I have to be able to use the arrow keys to navigate around like you do in a spreadsheet, type to add values and (simple!) formulas, and have the tables update instantly as necessary.

I noticed Linux has a text-based fossil called "SC" which would be perfect for my purposes, but it's not on Homebrew. Emacs packages would be OK as long as they don't require learning LISP.
