Removing actions from the edit form

Hi Steve
I am sure this information is available, but I can't find it - or perhaps don't recognise what I have found
I need to remove actions such as new, copy etc. from specific users for specific tables.
Can I put the code into a table.php for the table?
And is the code the same as for an application wide function?
(The reason is that I wish some users to be able to edit records that an administrator has set up, but not to create new ones.)
Many thanks
Neil
