The line is very clear, it's on the right side just below the orange circle. I found it difficult to understand the geometry of how it could be there given that the table appears to extend to the right just under that line. But you can set the edge and it's not actually the table extending, instead that is likely catching a bit of a camo jacket like you can see in the Instagram post sitting on a chair in just that location.
