Skill: Spreadsheet (formerly Spreadsheet software)
A program that manipulates tables consisting of rows and columns of cells, and displays them on a screen; the cells contain numerical information and formulas, or text. Each cell has a unique row and column identifier, but different spreadsheets use different conventions so the top left-hand cell may be A1, 1A, or 1,1. The value in a numerical cell is either typed in or is calculated from a formula in the cell; this formula can involve other cells. Each time the value of a cell is changed by typing in a new value from the keyboard, the value of all other cells whose values depend on this one are recalculated. The ability of the cells to store text is used to annotate the table with column headings, titles, etc.
