Your customers' browsers are at the end of a long line of potential bottlenecks . The power of the computer their browser is running on. Unnecessarily large Web pages just add another potential snag to this list. Wisely Most Web pages use tables to create appealing and useful page layouts. Clean, simple HTML coding and imaginative layout can speed the loading of the content that appears in the tables on your pages .
Browsers load the layout of each table before loading the content into it.
If you put all the content on your page into one table, then your customers will see only a blank page until the layout of the page is completed. Your customers may get impatient and leave while the page finishes loading, or they may think there is something wrong with your site or their computer. You can prevent this problem by using a layout composed of several different tables. Webmonkey has a page that shows you how to do this . Specifying the width of all your tables and each of their cells helps the browser render the tables more quickly.
