Hi Friend,

Try the following code:

<html>
  <script>
function addRow(){
  var ptable = document.getElementById('ptablePerson');
  var lastElement = ptable.rows.length;
  var index = lastElement;
  var row = ptable.insertRow(lastElement);

  var cellText1 = row.insertCell(0);
  var element = document.createElement('input');
  element.type = 'text';
  element.name = 'person' + index;
  element.id = 'person' + index;
  element.size = 30;
  cellText1.appendChild(element);

  var cellText2 = row.insertCell(1);
  var element = document.createElement('input');
  element.type = 'text';
  element.name = 'person' + index;
  element.id = 'person' + index;
  element.size = 30;
  cellText2.appendChild(element);

  var cellText3 = row.insertCell(2);
  var element = document.createElement('input');
  element.type = 'text';
  element.name = 'person' + index;
  element.id = 'person' + index;
  element.size = 30;
  cellText3.appendChild(element);

  var cellText4 = row.insertCell(3);
  var element = document.createElement('input');
  element.type = 'text';
  element.name = 'person' + index;
  element.id = 'person' + index;
  element.size = 30;
  cellText4.appendChild(element);

  document.getElementById("psize").value=index;
  }
function removeRow(){
  var ptable = document.getElementById('ptablePerson');
  var lastElement = ptable.rows.length;
  if (lastElement > 2) ptable.deleteRow(lastElement - 1);
  if(document.getElementById("psize").value>1)
    {
       document.getElementById("psize").value = 
           document.getElementById("psize").value-1;
    }
}
</script>
<form >
<input type="hidden" name="psize" id="psize">
<table style="border:1px solid #000000;" bgcolor="#efefef" 
  id="ptablePerson" align="center">
<tr>
<td><input type="text" name="person1"  id="person1" size="30" /></td>
<td><input type="text" name="person1"  id="person2" size="30" /></td>
