Here I wonder what criteria you use. We both look at a table.
Meaning is use.
Normally talking about a table takes place in a certain context. You even learned the word in different sequential contexts. Alter grew up with fashionable restaurants in national parks where logs used as tables were so common that he included them in his concept of table. So both found out, that they had a different understanding or use of 'table'. Now they can negotiate which concept to use for further communication, that including or that one excluding logs.
