Hello C R,

Thank you for posting in our community.

I tried following the scenario that you described and created a small sample. I enabled Multi Colum Headers and Resizing features. When I resize any column(from both multi column headers and regular columns) everything works as expected and all data iscorrectly displayed.

If this is not an accurate demonstration of what you are trying to achieve please feel free to modify it and send it back to me along with steps to reproduce. This is going to be highly appreciated and will help me investigate this matter further.
