I find using table so easy for layouts. Though I know how to use Div as well but using table makes my work faster. Is there disadvantages of using tables. What are the advantages and disadvantages of using both?

Though I know how to use Div as well but using table makes my work faster.

Do you read the Bible? If you do, are you familiar with the portion that says (in part), "straight is the road that leads hell"? My point: Making work faster isn't always equated with making work efficient.

Here is the answer to your question, in a nutshell:

Use tables only when you are presenting tabular data on your page(s). Don't use it for layout because:
1) Tables weren't originally meant for layout
2) Tables add unnecessary weight to your pages which means those will low bandwidth will take forever to download such pages
3) Using tables for layout makes the code harder to read and maintain, especially if you don't indent

Good luck!

Somehow, i dont believe table is faster at all.

Imagine doing a sidebar like this

[sidebar style='width:cvcvc;float:left']
html markups including table and td. . .up to 1000 lines
[/sidebar]

If you do the same with tables, you will start looking for where
one TD ends and another starts. But if you are using dreamweaver sha, you can always use the expanded tables layout.
But if you work in various environments like me, you will find out that you cannot do that all the time.

Then, for compatibility with lots of downloaded scripts, mobile phone compatibilities and several other things, i find DIV
layouts very very good.

And like yawatide said, tables were not originally meant for layouts, it just looks like the easiest way out kind of.

Thanks for all the answers. I checked nairaland source, and other forums; they are 80% tables and despite that, their speed to load is still faster compare to www.yahoo.com.

Regarding to being hard to read, you guys are absolutely correct.

1) Have you compared the SMF version of this NL versus the current SMF version?
2) Bandwidth isn't just about tables. Do you know if other optimizations have been carried out, behind the scenes?
3) I assume you are aware that yahoo.com does a lot more "work" than NL does.
