Autosize columns

Hi,

I have a simple question: How did you configure the grid for the demoApps/dhtmlxRSSReader application?
My goal: I want to have a grid, which is able to vertical resize with my browser window. When the grid is resized, I would like to have some columns with a fix width and some other columns which dynamically shrink/expand their size.

How can I do this? (I have not found any example code for this)

Thank you in advance
Chris

Unfortunately such feature is not available in dhtmlxGrid.
