adjust width of collumns in montage

I’ve searched the forum for something quite basic but I couldn’t find any topic. It looks like it is not possible to adjust the width of the collumns in the ‘Files’, ‘CD’, ‘Clips’, etc. tabs in an Audio Montage. I tried to double click the borders between the collumns (like in Excel), but this doesn’t work. Does anyone know how to do this?

The fields are auto-sized according to contents.
When is this approach a problem for you?

I thought so and a lot of times it works properly, but right at this moment I’m scrolling down the list of cd tracks and the width of the collumns “Name” and “CD-Text” is not properly adjusted.
