From an English background, I imagine we are sitting at a meeting. Something that is tabled is between us and under discussion. Something shelved has been removed from the table. What things are Americans visualising here when they say table?

It comes from picking something up to discuss and setting it down when discussion is over. I don't know how many people visualize anything when they say it.

As long as you are all happy with this. I'm still a little bit worried that the issue is Right There On the Table:)

I’m probably confusing people with my name and they expected me not to be using American English.
