I am using excel 2007 and the file format is xlsm. When I click on one column header two additional columns are activated. Example: I click on column "C" header to highlight the entire column and columns "D" and "E" are highlighted. I only would like to highlight one column at a time. I have looked at settings in the office button, but did not see anything. Aprreciate any assistance on this. Thank you in advance!!!
