Copy or Clone data from one pageblocktable row to another

Question

I am creating rows dynamically in my vf page.. In that row i have two picklist fields and 7 text fields.. I want when i will press copy commandlink the values from previous rows will get copied to the current one.

On initial page load , 5 rows default is created..

Hence i am finding difficult how to find which row index i need to copy..

Can anybody share some examples..

I have kept evrything in a wrapper class..Below is my controller. I need a method for copyrow values.

<apex:commandLink value="Copy" action="{!cloneWrappeer}" reRender="pb">
                            <apex:param assignTo="{!chosenRow}" name="chosenRow" value="{!acc.index}"/>
                            </apex:commandLink>

acc - is my wrapper class var in pageblocktable.. Custom_Package__c is my object and i have field like -

Name - Market - State -

attendeeList1 - Wrapper class instance..How to copy the fields..

 public void cloneWrappeer(){

        for ( Integer i = 0; i < attendeeList1.size(); i++ ) {


    }
}

I have added snippets below that will do what you need. I have included VF markup for a column in an apex:pageblocktable, id=units, with a commandlink and param attribute; also a snippet of apex code to copy the data from one row to the others. I am presuming that the blank rows already exist in a collection. In this case my collection is called units and the object type is Unit__c - obviously change as necessary.

VF:-

<apex:column rendered="false">
   <apex:commandLink value="Copy to other rows" action="{!copyRow}" reRender="units">
   <apex:param assignTo="{!chosenRow}" name="chosenRow" value="{!unit.id}"/>

   </apex:commandLink>

Apex:-

public list<Unit__c> units{get; set;}

    public id chosenRow{get; set;}
public void copyRow(){

//      system.debug(chosenRow);

        Unit__c chosenUnit;


        for(Unit__c unit : units){

            if(unit.id == chosenRow){
                chosenUnit = unit;
                break;
            }
        }
        for(Unit__c unit : units){
            unit.field_1__c = chosenUnit.field_1__c;
            unit.field_2__c = chosenUnit.field_2__c;
            ...


        }
        chosenRow = null;
    }
