Cellpadding is an attribute of an individual cell in a table, so each cell in a table can have its own cellpadding value.〔(How to Specify Table Cellpadding and Cellspacing in CSS | Easy Programing )〕 The cellpadding attribute was added to version 2.0 of the HTML language in 1996.〔(RFC 1942 - HTML Tables )〕
Space between text and borders is an important element of web page design, because it improves the readability of text and visual appeal of graphics in table cells.〔Goodman, Danny. (HTML: The Definitive Reference'' )〕 Cellpadding makes this possible, and web design experts emphasize the importance of carefully selecting the cellpadding values.〔(Cellpadding and Cellspacing - The Pocket HTML Tutorial )〕 The same effect can be accomplished in CSS.〔(How to set cellpadding and cellspacing in CSS? )〕
Presentational HTML elements such as cellpadding are becoming obsolete, as more and more web designers move to the use of CSS and other newer methods of creating web pages, available in HTML versions 5 and newer. One reason for this is that, although cellpadding makes reading easier for sighted users, text-to-speech software for non-sighted users has difficulty in interpreting complex table data. However, because visual spacing of text in tables is still important, developers of these newer methods continue to use the term "cellpadding" or "cell padding" to describe whatever process is used to provide it.
