TABLE布局还有个特性就是浏览器打开的时候必须是浏览器下载以<TABLE>开始, 并以</TABLE>结束后, 才显示该块的内容, 而DIV的HTML是边加载边将内容呈现到浏览器上。因此, DIV+CSS网站大大增强了用户的体验效果, 网页多等1秒钟都会增加浏览者等待时间。网页打开速度。特性决定性能, 因为DIV+CSS页面是DIV的HTML和CSS文件分开的, 而浏览器打开该网页的时候是同时下载HTML和CSS, 所以可以提高网页打开速度。
TABLE布局中大量样式设计代码混杂在表格、单元格中, 使得可读性大大降低, 表格中到处留下设计的足迹, 生成的网页代码除了表格本身的代码, 还有许多无意义的透明gif占位图及其他元素, 文件量庞大, 最终导致浏览器下载及解析速度变慢。
