In the left hand column of my budget spreadsheet I have the various
categories of income and expenditure listed with their relevant dates etc.
This is fine when I am on the same page as the left hand column however, once
I scroll across I lose sight of what each row corresponds to and they simply
become numbers.

How do I create a left hand margin or column which will scrioll along almost
like a picture frame around my work so I can always see what each cell
relates to more clearly?

Many thanks
