你有曾聽過 Quattro Pro. 有人說過
"A notebook can be set up to have 18,278 sheets, 18,278 columns, and 1,000,000 rows, for a total of 334,085,284,000,000 cells, plus an object page which stores copies of all the charts, graphs, custom dialogue boxes and maps."  是以前Borland的出品. 相信當時能和Excel杭衡的spreadsheet.  Borland完了, 相信知道的人不多.   它現時收在  Corel WordPrefect Suite 內, 有免費試用版給你測試.
