setColumnWidth problem

Hello,

I was trying to add a filters to the table headers as it is described in the http://demo.vaadin.com/book-examples/book/#component.table.headersfooters.fakeheaders (I read that this is the only one solution) but I have problem with setting fixed column width.

Normal table looks like this:

But when I add this code setColumnWidth( “airlineLogo”, 120 ); where ‘airlineLogo’ is a generated column ,then it looks like this, no columns, no content:

I am using vaadin 6.7.0, I use my own theme which extends runo theme.

Thanks for any advice
