fixed column width in a table

[Mario Ospelt <mospelt student ethz ch>]

Hello,

I think this is a very easy to solve problem, but nevertheless I could 
not find a solution myself. I just want the table I've created to have 
fixed column widths. The content of each column is variable and 
therefore the width of the column does now change and depends on the 
width of the content. How can I fix the width of a column in a 
Gtk::Table (e.g. in pixels)?

Thanks
Mario
