Not really.  If you're talking about old, old browsers, and you give them
something like <div>s with CSS-P, it will flow it together in an old
mess.  If you're talking about old, old browsers, and you give them
<table>, at worst it does the same as lynx -- flows it together in one
big mess -- and at best it will lay out the page exactly as intended.

Here's why tables are better than CSS -- the semantic meaning is more
clear.  In CSS, _any_ element can be used for layout purposes; most
commonly it's <div>, the absolute most generic tag in the lot, short of
its close cousin, <span>.  A <div> or a <span> can mean, literally,
_anything_.

Now, take <table>.  A <table> can be one of two things:  It can be a
layout table, or it can be a data table.  Distinguishing between the
two, if coded correctly, is not all that hard; data tables, for example,
rarely are designed to fill the entire screen within a <body>, while
layout tables usually don't have captions.

Therefore, <table> is a _lot_ clearer, within the markup, at indicating
"this is a bit of markup which could be either a layout table or a
data table" -- two choices.  CSS-driven layouts use elements which
could be _anything_, from generic style groupings to content groups
to layout groups to indications of language change to anything else.
