To set fixed width for a column in GridPanel??

[lordofthexings]

I have a gridPanel that I m creating semi dynamically.
This is the static code of it:
The first column in from left (Search Button ) how can I set it to a fixed width?
The below should work right but it doesnt everytime the 1st column width changes?
Why is that happening
Thanks
