Hi Markus,
without a way to reproduce and debug it we can't help you much. Please
open a bugzilla about this issue. Are you using RAP 2.0? Is this happen
in all browsers - Firefox, IE, Chrome?
Best,
Ivan

I'm currently bringing our "setting" support (written for SWT table) to RAP. now in some cases this thing tries to hide columns by setting the width to zero. In some cases this works, and in some i get weirdly misaligned headers (see screenshots). Also it seems that /sometimes/ not even a zero width is required but table headers are expanded to fit the text in them (but really not always - you can see that in the first screeny).

i have added a workaround proposal to the bug. and i have a question about it:
i try to patch (using rwt.qx.Class.patch) the GridHeader class. when i do it before the GridHeader constructor ran for the first time, the prototype is empty (thus the new() in my patch). in that case the mixin will be applied to an empty prototype, and it will result in a reverse order of functions (the mixin is base() of the actual implementation in RWT). is this desired/known behaviour? i mean it works the way i have it, but "clean" is something else
