hide column [data: {}] with conditional?

   let user=$('#user').val();

 "columns": [
           //{ data: 0 },
           { data: 1 },
            { data: 2 },
           //here how can I do something like that?
           if(user=='admin'){
                 { 
                     "render" function ( data, type, row ) {
                     }
                   }           
            }else{
                //If you do not comply, do nothing.
             }
    ]

How can I do something like this?

what I want is that if the user is an administrator,
Show me the action buttons.
if it is another user it does not show anything.

thanks for the answers
