Below is code I am using in a worksheet where the following are headers:

Columns: A1:H1
Rows: A2:A100

Right now, the entire row 1 and the entire column A are filled with the
color I have selected in the script which brings all into the print area.

Can you tell me how to specify the ranges to just the headers, instead of
the entire columns please?

Thanks in advance,

Scott
