'Twas written:

"The table is definitely a data-table with contents of a cells being
related to cell contents in adjacent cells."

"Sailesh, where are you taking this definition from?  I think I like it."

"Sailesh: I have always maintained this and had proposed to WCAG-WG in one
of my posts. And just a few weeks ago I read an extension to that to define
a layout table- if a cell can be moved around such that it does not affect
the  comprehension of the table, then it is a layout table."

I was just poking around the W3C site and came across the following in the
WCAG 1.0 glossary:

Tabular information
When tables are used to represent logical relationships among data -- text,
numbers, images, etc., that information is called "tabular information" and
the tables are called "data tables". The relationships expressed by a table
may be rendered visually (usually on a two-dimensional grid), aurally
(often preceding cells with header information), or in other formats.

----

If relationships exist, whether or not in adjacent cells, it's probably a
data table and headings ought to be identified in some fashion. While one
could always make their own interpretations -- and most people seem to do
this regularly, the table heading element in HTML works fine as the most
simple and elegant solution.
