Allow adequate space between lines of text in the cells and their borders for good legibility. If you consider borders with beveled edges, evaluate how the depth illusion works with other such dimensional elements on the page. Table border attributes can be used, on the other hand, to give a matted or framed look to a single image or group of images. Tables can also be used without borders. This is one way to achieve a multi-column text layout.
Borderless tables are usually more effective even for presenting traditional tabular data.
All HTML tags, including links and images, work within a table format.
