It works for me both in code and using designer. You also filled the MappingName (tableName) for DataGridTableStyle (in collection editor), right?
Do you want me to post a sample c# code?

>>You set the width properties but did you also set MappingName ? Probably that style is not used at all. If in use you should get the widths as you resize:
