- Tables and spacers (usually transparent single pixel images with specified width and height) are the old way to create and maintain page layout.
- Web pages designed with tables nested within tables, result in large documents which use more bandwidth than documents with simpler formatting.
- When a table based layout is parsed by a screen reader or a search engine, the order of content is jumbled and confusing.
- Web browsers usually have to download all content within a table before displaying it on a page, resulting in slower load times.
Without tables, content on a page can load sequentially, appearing faster to the end user
