dear frds i need
some info reg: dynamic row generation
how to generate a new row
at the end of the table at last field when i press tab or enter keys it will automatically generate a new row

You need scripting language for think like this as you need to run sort of loop cycle, I would say PHP would be your best solution, JavaScript may be to complex. However all depends on your experiences

Let's say you have:

		<table id="myTable">
          <th colspan="2">Phone</th>
        <td><input type="text" name="newname" /></td>
        <td><input type="text" name="newphone" /></td>
        <td><input type="button" onclick="addContact()" value="Add"/></td>

You can create a function like:

<script type="text/javascript" languaje="javascript">
function addContact(){
   var myTable = document.getElementById("myTable");
   var newTR = document.createElement("tr");
   var newName = document.createElement("td");
   newName.innerHTML = document.forms[0].newname.value;
   var newPhone = document.createElement("td");
   newPhone.innerHTML = document.forms[0].newphone.value;
