In all spreadsheet programs including Microsoft Excel, rows are labeled using numbers (e.g., 1 to 1,048,576). All columns are labeled with letters starting with the letter A and then incrementing by a letter after the final letter Z. For example, after the letter Z, the next column is AA, AB, AC, ..., AZ and then incrementing to BA, BB, BC, etc. all of the way to the last column XFD. When working with a cell, you combine the column with the row. For example, the very first cell is in column A and on row 1, so the cell is labeled as A1.
Tabular format is simply information presented in the form of a table with rows and columns. Most office productivity software programs, such as word processors and spreadsheets, include tools for entering text and data in tabular format. You can then enhance the appearance of the table by adjusting fonts, borders, backgrounds and other visual features. A data table is a neat and convenient way to present a large body of information that includes repeating data elements. For example, each entry in a list of company clients contains the client s name, title, address, phone number and other identifying information. This information can be listed in tabular format -- that is, in rows and columns -- by using separate columns for each data element. Columns are usually identified with headers such as "Client Name," "Street Address" and "Email Address," and each row contains all the information for a single client.
