It's fairly simple. First of all, what text is there to be aligned?
In HTML neither <COL> nor <COLGROUP> has text.  Because
inheritance works only from parents, a table cell can't inherit
from the column or the column group element unless inheritance
is fundamentally changed in a way that would make it far less

However, not all is lost.  If you don't make use of the colspan
attribute in HTML, you can style columns using the :nth-child()
and related pseudo-classes.  tbody>tr>:nth-child(odd)
can be used to select the cells in every other column of a
table that did not use colspan for any of the cells in the body
of the table.

Unfortunately, neither Gecko nor IE supports this yet.
You can use the + combinator to approximate the missing
:nth-child in Gecko (and if you are trying to style just the first
or the last column :first-child and :last-child are available.)
IE will let you attach style to the <col> and <colgroup>
elements which the cells will inherit, but that in part is
because IE doesn't use CSS to determine what is a table
part, so determining which column a cell is in is much simpler,
altho less flexible.
