Change URL icon image or concatenate with text?

I think I got a solution for you. Ok, a workaround.

 

First you need both the target URL and the image URL

Then categorize the image URL column as Image URL so the image gets rendered.

Next, change the Image URL value's conditional formatting to format the column by a Web URL

Lastly, make the condition based on the value in the other column

 

And there you have it - a clickable image in a table !
