[Javascript] visibility of a table column

I need to set the visibility of an entire column to hidden or
visible. I was hoping that the following would work:
<table>
<colgroup>
<col id="col1">
...
</colgroup>
....
</table>
<button onclick="document.getElementById('col1').style.visibility = 'hidden';">
Hide Column 1
</button>
However, when I try it, it doesn't work. Is it supposed to? I realize
that I can set the visibility of all cells in that column, but it
might be a very large table. I am using Firefox.
Actually, while composing this e-mail, I decided to try this under IE
6. It sort of works. It hides the contents of the cells in that
column. However, it doesn't make the column go away - in fact, the
column retains its former width, so I assume it's computing that
width from the data, which is still really there. To be honest, this
seems like an odd solution, since it's the column's visibility that
I'm setting, not the content of the column's cells. Does anyone know
what the behaviour is supposed to be?
