Hi John,
To your first question, yes I used the measure “Cell Width” to achieve the same cell size. There are a couple of videos on you tube to follow - quite simple but I recommend watching one these videos.
To your second question, I use this website and it zero-widthspace code. Copy to clipboard, click twice in the measure “Like you want to change its name” and paste the code.
I hope this helps and happy to help too.
