The fundamental unit of a spreadsheet is its table, containing cells organized in rows and columns. Each cell contains information or a formula. In a simple spreadsheet, the formula refers to the contents of a cell in another column, while one cell in the same row or column refers to the value in that cell. A single cell in a spreadsheet can be referred to by its row and column name, or by its reference number. This concept was first introduced in LANPAR (a computer program invented by Remy Landau and Rene Pardo), while the formula itself refers to a set of cells.
A spreadsheet is an electronic program that displays data in a two-dimensional tabular format. It is used to display numerical data, such as credit card payments, and can also be used to calculate repayment plans. The first electronic spread sheet is a program called VisiCalc, although this has been challenged in recent years. When DOS was the dominant operating system, Lotus 1-2-3 was the leading spreadsheet. Today, Excel holds the largest share in the market for Microsoft’s software.
