Definition: Columns are a fundamental part of any spreadsheet program such as Excel. Columns run vertically in a spreadsheet and help to identify the location of
data. Each column is identified by a letter in the
column header.
There are 256 columns in an Excel 2003 worksheet. In Excel 2007, there are more than 16,000.
The intersection point between a column and a row is a cell.
Cells are the basic storage unit for data in a spreadsheet.
Examples:
If the number is too wide for the cell, widen the column so that the entire number can be seen.
