As ralph.m says, you would be much better off learning to code for yourself. It's really not that difficult.
If I've understood your question correctly, you want to insert a separate table next to your existing one, but Dreamweaver is inserting it inside your existing one. Is that correct? I'm guessing here, but it sounds as if maybe you still have the first table selected in some way when you try to insert the new one. Make sure you are completely outside the original table area first.
Just out of interest, why are you trying to insert a 1x1 table? That would just be a single cell, which doesn't seem to me to be a table at all.
