VF page pageblocktable

Hello,

I am new to salesforce development, can any one help on this?

Q: I want vf page pageblocktable should contain 3 columns, in that first two columns is from custom object and values for this columns is pulled from custom object. And 3rd column is result(SUM) of 1st and 2nd column(3rd column doesnt belong to custom object, it is independent column which is used to display result only)? Need help to create this process.


Regards,
Ram

Use Wrapper class 
refer apex class and vf page 
public class customController
{
    public  List <customWrapper> customWrapperList{get;set;}
    public   void loadCustomObj()
    {
 
        customWrapperList= new List<customWrapper>();
   
  for(Contact c : [select C1, C2  from customObject)
            {
                customWrapper cw = new customWrapper(c.C1,c.C2,  c.C1+c.C2 );
                customWrapperList.add(aw);
                
            }
        }
     
    }
    
    public class customWrapper{
    public  String C1{get; set;}
    public  String C2{get; set;}
     public  String C1C2{get; set;}
        AccountWrapper(String C1,String C2, String C1C2)
        {
            this.C1= C1;
            this.C2= C2;
            this.C1C2= C1C2;   
        }
    }
}
  
<apex:page controller="customController" action="{!loadCustomObj}">
<apex:form >
    <apex:pageBlock id="details">
    <apex:pageBlockTable id="table" value="{!customWrapperList}" var="cw">
     <apex:column value="{!cw.C1}"/>
    <apex:column value="{!cw.C2}"/>
    <apex:column value="{!cw.C1C2}"/>
    </apex:pageBlockTable>
      
    </apex:pageBlock>
</apex:form>
</apex:page>

You need to utilise wrapper class in this case. Below is the code sample: 

Controller:  
public class myController
{
	public List<helperClass> helperList {get; set;}

	public myController()
	{
		List<My_Obj__c> obj_list = [Select Id, col1__c, col2__c From My_Obj__c];

		for(My_Obj__c obj: obj_list) 
		{
			helperClass helper = new helperClass(obj.col1__c, obj.col2__c);
			helperList.add(helper);
		}
	}

	public class helperClass 
	{
		public Integer col1 {get; set;}
		public Integer col2 {get; set;}
		public Integer col3 {get; set;}

		public helperClass(Integer col1, Integer col2) 
		{
			this.col1 = col1;
			this.col2 = col2;
			col3 = col1 + col2;
		}
	}
}

Then you can use <Apex:pageBlockTable> to display the values in helperList.
