mail merge using one tab

I have several tabs in my database. When I did labels I was able to choose the “table” I wanted to use. But in the form letter I don’t see a place to do that. Also in Microsoft I was able to use only the print area. Is there a way to do this?

Okay, found how to do tables, but still don’t know how to do only print range. I just created a new sheet (table) in my spreadsheet and I did get it, but it seemed to show 87 pages when I only needed 20. I just printed the ones I needed. Would still like to know how to only print out the letters for records in the print range.
