When I export the product fields after creating a couple of sample products the result is the maximum number of columns in excel (256 in the older version I am using) all filled with column headings; mostly options, etc. I am wondering if just the product headings in the import/export section of the manual are the ones that I need and if so, can I just include them in my csv file to import or are some of the 256 headings required?(I'm using the latest version Abantecart 1.2.2
