Change like below and use this code .. you have three argument constructor and you are not using correctly

the constructor  will accept the Order, Opportunity and Cost Price objects 
 
public with sharing class costsheet {
 
 public costsheet(ApexPages.StandardController controller) {

    }

 public List<Order> ordwrap = new List<Order>();
 public List<Opportunity> oppwrap = new List<Opportunity>();
 
 
 
 public costsheet()
 {
  this.SOWrappers = new List<SOWrapper>();
  ordwrap=[Select id,Cost_Price_As_per_Allocation__r.CI__c from Order];
  oppwrap=[select Id,name,Account.Name from opportunity];
  for(opportunity opp:oppwrap){
                for(Order ord: ordwrap){
                    If(opp.id == ord.id)
                    {
                        SOWrapper wrapper = new SOWrapper(ord ,opp ,opp.Cost_Price_As_per_Allocation__r );
                        this.SOWrappers.add(wrapper);
                    }
                        
                    }
                }
 }
 public List<SOWrapper> SOWrappers{get;set;}
 public class SOWrapper{
        public Order order{get;set;}
        public Opportunity opportunity{get;set;}
        public Cost_Price__c costprice{get;set;}
        
        public SOWrapper(Order ord, Opportunity opp,Cost_Price__c cp){
            order= ord;
            opportunity = opp;
            costprice = cp;
        }
    }
    
}
