MouseOver on an entire Column in a table

[Catriona McCann]

Hi,
I am building a HTML table dynamically from XML using XSL. In this table I have popup menus (also populated dynamically - visible on mouse over).
The column names are the div names - this works fine if only one row in the table but if more than one row I get errors as multiple divs have the same name (id).
Is it possible to define a div for an entire column??
Any ideas ?
Catriona.
