I’m starting to think this is not possible.
As you can see in the image, column C and D are merged after the first two rows, same for E/F and G/H. Now, my problem is that the sorting option is a bit annoying. Because of the merged cells, if I try to sort the cells with the little button next to “Series”, “Authors”, etc. I get the “Ranges containing merged cells can only be sorted without format” error.
Now, I can bypass that by going into the sort options and manually untick the “Include Format” option, but I have to do it everytime I want to sort my list because it always rechecks itself automatically. I was wondering if there was a way to just disable that “Include Format” option permanently so that I can easily sort my list with the buttons.
I know I could just unmerge the cells and try another configuration, but I like how it all looks right now, that sorting problem is the only annoying thing that I can’t figure out.
I hope my question is clear, I’ve been working on this for a while and my brain’s a bit fried.
