How can i stop users inserting and unhiding rows and columns my workbook

[G20EGG]

Hello,

I am currently creating a new file for my work and i want it to have
the feature where on some sheets of the workbook the users can not
insert rows/columns , delete rows/columns , hide rows/columns. i do not
really want to protect the sheet. does anyone have any marco i can run
to stop these features being used on certian sheets in excel.

also is there a way without protecting the sheet to protect all the
formulas in the workbook.

thanks in advance

Gregg
