So I cheated a little, because I'm at a table right now, so I didn't visualise the table just the ball on the table. It was about tennis size, but no texture, kind of light blue shading into lilac. The person pushing it was really just a hand.
So sounds like the only work I did was imagining the ball. I wouldn't say I knew in advance, and I wouldn't say I chose what it looked like. It just appeared and it was light blue.
Edit: the ball started rolling when pushed, but not long enough for me to know whether it fell off the table or not. But the rolling was just a concept. I can visualise things, but I can't visualise motion. Which I only discovered recently.
