The below example should get you started on what you want to achieve. You can try it out separately as it uses the standard Account and Contact objects.

Page:

<apex:page controller="NestedTableLogicClass">
<apex:form >
<apex:commandButton value="Add Outer" action="{!addOuter}" rerender="panel"/>

<apex:outputPanel id="panel">
     <table>
     <apex:repeat value="{!myWrapperObject}" var="key">
      <tr>
        <td><apex:inputField value="{!myWrapperObject[key].objectVar.Name}" /></td>
        <td><apex:commandButton value="Add Inner Row" action="{!addInnerRow}" rerender="panel">
            <apex:param value="{!key}" name="row" assignTo="{!row}"/>
            </apex:commandButton>
            <table>
              <apex:repeat value="{!myWrapperObject[key].innerList}" var="innerListVar">
                <tr>
                  <td><apex:inputField value="{!innerListVar.lastName}" /></td>
                </tr>                
              </apex:repeat>
            </table>
        </td>
      </tr>
     </apex:repeat>
     </table>
</apex:outputPanel>
</apex:form>
</apex:page>

Controller:

public class NestedTableLogicClass{

  public Map<Integer,WrapperClass> myWrapperObject{get; set;}
  public Integer counter {get; set;}

  public Integer row {get; set;}

  public class WrapperClass{

    public List<Contact> innerList {get; set;}
    public Account objectVar{get; set;}

    public WrapperClass(){      
      this.innerList = new List<Contact>();
      this.objectVar = new Account();
    }
  }

  public NestedTableLogicClass(){
    counter = 0;
    myWrapperObject = new Map<Integer,WrapperClass>();

    /* Adding one outer row on page load*/
    addOuter(); 

  }

  public void addOuter(){
    counter++;
    myWrapperObject.put(counter,new WrapperClass());

    /* Add one inner row everytime an outer row is created */
    row = counter;
    addInnerRow();
  }

  public void addInnerRow(){
    myWrapperObject.get(row).innerList.add(new Contact());

  }
}

@miku if you want to add one outer and inner row, simply call the two methods in the class constructor. I have updated the code accordingly. — AslamK
