The time to use tables is with tabular data.

I think learning how to build sites in tables is a good way to start. It helps your mind piece together designs. Once your decent at it, switch over to divs

First of all, Divs are part of the web standards and you should definitely design your pages by those standards.
By doing so you get better SEO as you are able to seperate information from the structure of your website. Webpages also become lighter when using divs (css) instead of tables. The ease of maintenance also improves as you don't have to individually change every page but you can just change the style.css file.

Hope this helped.

If you are making a ridiculously simple website, then tables might be OK.... but if you are beginning a project that you want to develop, or even has the slightest possibility of getting additional content being added, you are going to wish you had used div tags instead. It is MUCH cleaner programming. It helps with SEO. Adheres to web standards (always a good thing). And it is much better at differentiating the different sections of your website.

The most important advantage from my point of view is its flexibility as it is much easier to modify a site later using div layout as compared to table layout.

There's an awesome Smashing Magazine article about this at
Table Layouts vs. Div Layouts: From Hell to… Hell? - Smashing Magazine

This has been one of the biggest issues in design community for years.

Here are couple advantages from the top of my head:

- screen readers - people with impaired vision that use audible readers can browse your website normally where in Table layout it gets all messed up. Most of the Government and Public service websites are done with Accessibility in mind.

- mobile browsing or browsing on smaller screens can cause tables to act unpredictably. Most smartphone can adjust autozoom based on your divs; doesn't exactly happen with table.

- divs sizing is independent of each other. Once you start nesting tables, making one cell bigger pushes adjacent cells to be bigger too.

BTW, great link SJL!

also HTML should be written in XML format. By using table for "visual" representation in HTML code is not very XML-ish. CSS must dictate formatting, not XML code.

Divs along with good CSS formatting give you far more control over how your content looks and how's it's rendered to the end user...

I used to be all tables when I very first started out but once I got my head around divs I never looked back

If you're learning how to design websites for a living then you'd best learn how to use div's.

If you're building quick websites for yourself to earn a side income, you'd still better learn how to use div's.

Why? Because you'll thank yourself later with all the time you will have saved from using the right method to build a website.

Use div's, float them as needed, and don't think that anyone has mentioned, but you will want to get yourself cozy with the "clearfix" CSS code...will save you lots of headaches trying to figure out why your divs are on top of one another...read this:
