Using numerous tables in a single page, is it a problem?

If i use multiple tables on a page say 15 t开发者_如何学运维ables in a single page then will it affect page performance?

Any data on a page effects page-performance. Nothing loads faster than something all the time. The question, instead, should be "Am I using tables when I should be," or "Should I be handling this data differently?"

Imagine another question, "Can this platform support the weight of 15 things?" I think you would rightly ask me "That depends, how much do they weigh?"

Regarding Layouts

From your comment on the OP, it appears you're interested in this topic as it applies to layouts. In that case, yes. It does matter. Divs are the proper method of doing web-page layouts, and Tables are reserved for tabular data.

I'm not sure if this still applies but I remember IE used to not display a table until the whole table had loaded.

It will be bigger in KB than to do it with ul or div tags ... but i dont think that you will notice the diference.
