title: Extracting parts of data from a google spreadsheet to a google document
body: <p>i have a google spreadsheet which has the following 7 columns: 1) room number, 2) waiter 1 name, 3) waiter 2 name, 4) waiter 3 name, 5) waiter 1 experience, 6) waiter 2 experience, 7) waiter 3 experience. i want to create a document or pdf from the spreadsheet with just 3 columns: 1) room number, 2) waiter names, 3) waiter experiences. That is, it should be in such a way that the waiter names and waiter experiences for all the 3 waiters is one below the other for each room. The data is now presented in only 3 columns instead of 7. Any clues how do i write a google apps script for doing this?</p>
