where 'alpha' is a unit of measurement for the width of a spreadsheet, a 'one alpha' is a small spreadsheet. ie it only uses the columns A through Z or less. expressed in notation as 1A.
the term is also adapted to larger spreadsheets, eg two alpha (2A), five alpha (5A), etc., and it is worth noting that excel 2007 can accommodate slightly more than a six hundred and thirty alpha spreadsheet (which is technically a six hundred and thirty one alpha), because six hundred and thirty two alpha is just being ridiculous.

eg: the numbers are pretty clear; i'll have a one alpha to you by lunch
