4 nested Tables load slower than 2 nested table?

If i have a table within a table within a table within a table...or 4 nested tables..
does that load slower than just 2 nested tables?

Yes! Basically, it works like this:

A table will not display until ALL of the HTML for it has loaded. The simple reason for this is that it can't be entirely sure how the table will look until it sees all the code. So with nested tables, the outer table can't load until each subsequent table inside it has loaded.

So for quick load times, you should nesting to a minimum if you can.
