There are several reasons why web designers should stop using tables for layouts, and adopt the use of CSS for controlling HTML layouts.

☛ It adheres to current W3C web standards and it improves accessibility of the information to a wider variety of users, using a wide variety of user agents.

☛ There are bandwidth savings as large numbers of semantically meaningless <table>, <tr> and <td> tags are removed from dozens of pages leaving fewer, but more meaningful headings, paragraphs and lists.

☛ Layout instructions are transferred into site-wide CSS stylesheets, which can be downloaded once and cached for reuse while each visitor navigates the site.

☛ If coded well, CSS makes it easy to apply global changes to the layout

☛ Web pages often have less code, and are much thinner when XHTML and CSS are used

☛ Sites may become more maintainable as the whole site can be restyled or re-branded in a single pass merely by altering the mark-up of the specific CSS, affecting every page which relies on that stylesheet.

☛ New HTML content can be added in such a way that consistent layout rules are immediately applied to it by the existing CSS without any further effort.
