How can I freeze (lock) my Spread Sheet layout in Numbers?

Question

How can I freeze (lock) my Spread Sheet layout in Numbers?
I have problems with Numbers changing my Spread Sheet layout
by adding extra Rows while I am not looking, or while I engage in dragging its pages with the mouse to see info on adjacent pages.
The layout I use consists of a Spread Sheet containing 4 "print" pages, ea.  8.5" x 11" wide, with a total of 36 Rows and 28 Columns. 
The SS is filled with new cell values daily, but the formulas stay mostly the same. The print pages are visible on the computer screen side by side, and each Row extends over these 4 pages.
It happens sometimes that I have to change a formula while making entries on a cell in "page 4", and then need to "accept"
the new entry and formula "aaalll" the way on the very left of "page 1".  So here I try to scroll left or drag the present view
with the mouse.  I also have to use the "Zoom" at 150 % because I cannot see well on my MacBook Air, everything is rather small.
I suspect that during dragging with the mouse I drag cells or rows without knowing, and that this will add extra Rows derailing some formulas or values because a cell is suddenly in a different Row.
It is difficult to find which Row was added and what values where thus changed.  One just sees 38 rows instead of the orihinal 36!  The only way is to move all the cell values out of rows 37 and 38, and find where theey used to be on the previous day's saved locked sheet.   Needless to say that when that happens twice in a days work, it means a lot of lost time.
I have checked the Numbers Manual and searched Help Info for ways to lock an established cell layout and could noy find anything.
I cannot believe it, maybe I missed something.  I worked for about 35 years with Clarisworks and Appleworks Spread Sheets and never had the same problem, layouts were locked by design, and could only be changed by special procedures.
Now is there a way to freeze or lock the basic layout of a spread sheet in Numbers? 
I appreciate your help.   (Numbers 2.3, Mac OS 10.8.5. MacBook Air)

Hi Numbers22,
I guess I was just beating around the bush to avoid simply saying, "No, you cannot lock the layout." So there it is.
I am not sure why you are scrolling  to "accept" a formula. That is unclear. I guess you building a new formula and need to use a cell from an early column. It is also unclear to me as ot how you are actually adding extra rows. I haven't been able to do it on my machine without clicking the little arrow in the row number or using Option-↑ (or -↓). Option-↑  would add a row above the row you are in if they somehow got pressed. Do you have a program running that could be interpreting something your are doing for those keystrokes? If I was standing at your shoulder I might be able to see what is doing it.
What I am suggesting is that you play around with your trackpad settings so that you are not selecting and tapping in your table while you attempt to scroll. I do have one sheet with two tables side by side with a total of 425 columns and I can scroll past them without modifying them. So perhaps turning off tap to click in system preferences will help. If you have an option to decrease trackpad sensitivity then try that (I don't, but I remember having it somewhere in the past). If you are using a mouse see what you can do to decrease the sensitivity for a click. If your computer is old it could be that the trackpad is wearing out and throwing random clicks. You might try using another input device if you have one.
