This is a problem that I have seen spanning all the way back from 2012 online.
I have a table with 1 <thead></thead> tag at the top containing multiple header rows. When I export the spreadsheet, it only exports the last row in the table header. Is there any code I can inject into the source code to get this feature working?
I have seen previous attempts at modifying the course code from various other threads on this site and Stack Overflow and none of them seem to work for me. I found the threads quite vague in their implementation of their code fixes, and I haven't been able to get it to work on my end. And, when I paste the code in I am not even sure what I am changing.
Any ideas on what I can do to get all header rows included in the Excel export?
