Modern spreadsheet applications allow for more than one two-dimensional "sheet," effectively stacking related spreadsheets on top of each other and introducing a third dimension.
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.
