Locking columns

[Sherry]

I want to lock columns so others can't get into the document and delete or
hide a column, however I want them to be able to add a row so they can fill
out the appropriate data in each column. How do I do this?

Protect your workSHEET with a password. When you select to protect it, a box
will appear asking what you want users to be able to do or not to do. Delete
columns and insert columns can be enabled/disabled seperately here.
