In the cell (not sure how to enter code in this post):
“<“a href=”www.aiellospizza.com”>www.aiellospizza.com</a”>” `
turns text into a link in the published page. The cell will accept any html.
However, the background color selector does not work.
It is possible to add a link inside the a cell through html markup. Just tried it and it works: test.com.
The word “test.com” is clickable and will open in a new window.
