I believe this would have to be done using a calculated field that is based on some other field besides the Nr and %. Are you able to post a sample workbook (twbx file)?
Thanks for the reply.
We use calculated fields to determine the column values and are named as follows:
Nr 1 day late
% 1 day late
The values is fine. Problem is the headings. All this long headings just take up too much real estate. We need a 'summary' heading that span 2 columns as displayed in the image. This will save massive real estate and willlook a lot better.
I will get a smaller version of the workbook to post.
