Creating Excel with EPPlus: Set Column Widths in Pixels and Add Logo

Question

Hello Friends;

I have a question for you, I want to pull the data according to id and process it with excell, I even want to add a logo

but I couldn't do it somehow, the thing is that I actually want to give the size to the columns and add a logo, but every

I'm having trouble sizing, the size I want is actually

Column A 97 px

B, C, D, E, F, G, H columns will be 41px, these columns will merge and the logo will be added exactly inside these merged columns.

public ActionResult Excel(int? id)

    {

        List<TBL_GenelBilgi> FileData = db.TBL_GenelBilgi.Where(x => x.GenelBilgiid == id).ToList();
