Column widths and linking worksheets

[Guest]

It has been a while since my Excel class in college and I am looking for two things. 1- Can I change the width of just ONE cell in a column, and if so how? Any change I try to make changes the entire column. 2- How do I link two worksheets together?
Thanks,
RAM

1 You cannot have different widths for cells in the same column.
2 Include the sheet name in the cell/range references, for example
=SUM(Sheet2!A1:A10)
