I'm not a fan of the spreadsheet paradigm, and unlimited columns even if you never use them, requiring lazy-initializing them on first access to avoid prohibitive performance penalties. I'd much rather define a set of global columns for each table (like a SQL database with computed view columns and a table editor attached, rather than a freeform canvas with a formula engine and automatic copy-paste attached).
