Oh, I only saw two tables, now I also see the middle one.

1. What is the proper way to see all the tables, I pressed Ctr+A then I hovered the mouse over the first column, but seems I did it too fast.
2. What procedure should I use for copy/paste a row to prevent the table from being split? (I copied a row from table1 with Ctr+C then selected a row in table2 and pressed Ctr+V (insert as new rows(R) what is the default). Did you do it differently?
