Separating Cells In A Worksheet

Set up a worksheet so that it has 2 separate sections in the same worksheet ????? I am wanting to have 2 different sets of information in the same worksheet - and need the columns to be different sizes based on the information i want to put in. Is there any way to have this done - as I know that if you change the column width it does all columns - and i only want to do select columns. For example for section 1 - i would like to have the column widths as follows:

A1 = 20
B1 = 40
C1 = 10
D1 = 20
E1 = 40
A3 = 20
B3 = 40
C3 = 10
D3 = 20
E3 = 40

This is where i want to put details such as names, dates and results.

Then for section 2 - i would like to have the column width as follows:

A6 = 10
B6 = 45
C6 = 15
D6 = 30

This is where i want to have a set of questions to answer.
