Jim,

If I understand your question correctly, I think you need to click on the box in the upper left hand corner of the table to select the entire table, then setup your borders in the inspector.

I put together a quick video to illustrate what I'm talking about.  Unfortunately, you can't see the mouse pointer, but hopefully it will help.

If this wasn't what you were looking for, please edit your question to add more detail.

Thanks,

Michael
