Sandraros/255 header

ZDEMO_EXCEL47 updated to demonstrate enhancement abap2xlsx/abap2xlsx#1051 for table headers with more than 40 characters.

This is how I see the generated output with Excel 2019:

Other than the formula error, possibly language or version dependent, the file is opened successfully.
Incidentally, I had a git pull error on the demos that matches the linter warning; in my case, it turned out that my abap2xlsx installation was a couple of commits behind upstream and bringing it up to date fixed the problem: could it be something similar for the linter? @larshp
IOW, this should not happen again without any changes, right?

Concerning the formula error with Excel 2019, it works with Excel 365, so I guess we should change the title of the demo program that it works only from Excel 365/Excel 2021 as confirmed by this Microsoft article. Added a commit with new program title: abap2xlsx Demo: Table Calculated Columns (from Excel 365 or 2021)):

Probably it would be better to use another program to demonstrate table headers, compatible with all Excel versions, and keep that one specific to only Calculated Columns, without demonstrating table headers, and compatible with only Excel 365/Excel 2021.

Concerning the lint failure, that happened minutes after merging the new field column_name in abap2xlsx repository, I imagined that happened because the merge was too much recent and the lint was reading the old commit, so I ran again the lint, and there was no more error.

Thought so, thanks for the confirmation on the linter issue.
Also, fully agree that demos should be split according to Excel version, when necessary.
Let's merge this one and deal with the rest as need arises.
EDIT: I don't have write access, this is weird.
