The Table Trick
As mentioned in "Website
optimization", a table-based layout
usually works well with search engines.
However, a traditional design that contains
the menu on the left and the content on the
right does have one downside.
In many cases, such a layout will cause
your navigation menu to appear above your
content in the source code. This is unlikely
to create any major problems, but might make
it slightly harder for your pages to obtain
good rankings.
Correcting this issue seems relatively
simple, at least at first. It can be done by
making some minor changes to the way your
tables are arranged. The procedure is widely
known in SEO circles as "the table trick".
Note that this article contains some
examples in HTML code. Hence, a basic
knowledge of HTML is necessary in order to
use this information to the fullest.
A normal table layout with the content on
the right and the menu on the left looks
something like this:
To switch the order in which the content and the menu appear in the
code, we'll need to make a few simple
changes:
As you can see, we've added one empty table cell and a new table row.
We've also included a rowspan=2 statement to
the table cell that contains the content.
Because the table cell we added is empty, it
doesn't cause major changes to what users
will see. It is only shown in the picture
above to make it easier to understand how
the code works. The content, however, now
appears above the menu in the source code.
Unfortunately, if you really want to use
the table trick, you'll need a more
complicated solution than this one.
Beyond the basic table trick
The table trick we presented above really
isn't suitable for use. If your menu is on
the top left and your content on the right,
just like this site does, you'd be happy for
a while. Until one day you'd write a long
article for one of your pages and notice
that

you would get this. |

When the length of the content greatly
exceeds the length of the menu, funny things
start to happen. The menu drops downwards,
which usually pretty much ruins the design.
However, there is a relatively simple fix
for this issue - just add "valign=top" to
the <td> statement the menu is contained in:
Now the menu should stay at the top, no
matter how long the content page is.
Because APG's design contains a
background image, we've also added one more
workaround to our table trick code.
As explained earlier, the table trick is
based on creating one empty table cell that
is positioned directly above the menu.
However, Netscape Navigator 4 does not apply
a background to a table cell that is empty.
So, we've added a
transparent 1x1 pixel .gif image to
prevent Netscape 4 from turning a small area
in top of the menu from grey to white:
Does it now work properly?
Yes, unless the visitor happens to use a
browser that is more or less buggy. The
navigation may still drop a bit in Netscape
Navigator 4 or some old (pre-5, but at least
v4 for PC should work fine) versions of
Internet Explorer. However, this should not
be a major concern, as only around 5% of
Internet users use those browsers and the
percentage is constantly decreasing.
Is it possible to adjust the table trick
to work perfectly with NN4 and those old
IE's? Probably yes, but I haven't found a
reasonable way of doing it. There are some
makeshift solutions that will work. However,
they require a lot of effort and may also
cause problems with other browsers. Just
comfort yourself with the fact that nearly
any kind of design will look broken on some
browser or screen resolution.
