[Orgmode] format table column

[plutek-infinity]

greetings!

i'm wondering if there is a way, within the org-mode table-formatting 
facilities, or within an org-mode css style block, to define text formatting on 
a per-column basis.
i.e. to make a table which, when exported to html, will have column A all 
center-aligned, column B all right-aligned, and column C all left-aligned.

it would, of course, be preferable to have the format definition somehow 
defined such that editing, removing, or adding rows to the table doesn't 
disturb the formatting -- i.e. anything added to column A becomes 
center-aligned, etc.

thanks, in advance, for any clues you may have!
cheers!
