Just a heads up: Anchors (that’s the #Part1E in your link) only work when the post number is referenced as well. Otherwise they only work from within the originating post. 
Edit: The correct link would be this: [Guide] Zodiac Rend (Season 20) which is https://us.forums.blizzard.com/en/d3/t/guide-zodiac-rend-season-20/79/1#Part1E when viewed via mouseover. As you can see, using the link from this page doesn’t work, but it you paste it into the URL bar while you’re already on the page, it works. Fun stuff.
Edit 2: Now I see what tripped you up. It’s the way RO is separated from RG in the table header. Looks like Free put a space between those two letters to shorten the table length. He’ll have to fix it though, as it isn’t a wiki guide so I can’t edit that confusion out of the table for him.
