Merging spreadsheet prob

[Excel learner]

Hi all:

I have a problem while merging two excel spread sheet.
When I merge the second .xls file with the first .xls
file,
my second .xls's file's sheet rows width are getting
affected.
It's not retaining its original layout like row heights
etc.

I would like to keep the same format of the second .xls
file after merging the with the first .xls file.

If anybody can keep me, it'll be appreciated.
