Here you are the code:
HTML Syntax (Toggle Plain Text) 
  1. <HTML><HEAD>
  2. <META http-equiv="content-type" content="text/html; charset=UTF-8">
  3. <TITLE>add/ed/del row</TITLE>
  4. <script>
  5.  
  6. function add(oRow) 
  7. { oRow.parentNode.replaceChild(oRow.cloneNode(true ),oRow.parentNode.insertRow(oRow.rowIndex+1));
  8.   var inpN = oRow.nextSibling.getElementsByTagName('input');
  9.   var inpR = oRow.getElementsByTagName('input');
  10.   for(var i=0;i<inpR.length;i++)
  11.   { if(inpN[i].disabled)inpN[i].disabled=false;
  12.     if(inpR[i].type=='text')inpR[i].disabled=true;
  13.     if(inpR[i].value=='add')inpR[i].value='ed';
  14.   };
  15. }
  16. function ed(oRow)
  17. { var inpR = oRow.getElementsByTagName('input');
  18.     for(var i=0;i<inpR.length;i++)
  19.   { inpR[i].disabled=false;
  20.   }
  21. }
  22. </script>
  23. </HEAD>
  24. <BODY><form method="post" action="./finalPage.php">
  25. <table><tbody><tr><td><input type="text" name="row[txt1][]"></td><td><input type="text" name="row[txt2][]"></td><td><input type="button" value="add" onClick="(this.value=='add')?add(this.parentNode.parentNode):ed(this.parentNode.parentNode)"></td><td><input type="button" value="del" onClick="this.parentNode.parentNode.parentNode.deleteRow(this.parentNode.parentNode.rowIndex)" disabled="true"></td></tr></tbody></table>
  26. </form><br>
  27.  
  28. </BODY>
  29. </HTML>
But! What will you do with the data after the formula is fulfilled? Is the data to be processed at the same page using another JavaScript? or there have to be a button for sending the data to a process page?
You asked for the change the button "add" into the "edit". What will you do after you'll be finished with the row editing? Could not be the "ed" button change into the "lock" button while editing the row?

Think it over, before you start to code and asking the help!

  13.     if(inpR[i].value=='add')inpR[i].value='ed';
  14.   };
  15. }
  16. function ed(oBut)
  17. { var inpR = oBut.parentNode.parentNode.getElementsByTagName('input');

  25.   for(var i=0;i<inpF.length;i++)
  26.   { inpF[i].disabled=false;

Save the page as the fuj.php and it shows you what you had input before send (if you have PHP module enabled on your server, of course).
See you after some hours :-)

Bravo Maan... exactly wht i looking for... but still there are few validation tht i want in it.... Can u guide me little bit...!!!
i will be thankful to u...!!!
Validation are like this-
1) At least one row and only one row should be Fillled before adding a new row..!!!Value must be integers..!!
2)At the bottom of table there are two textboxes which total the amount of textboxes in Table..!!
3)When Edit button is pressed then add button should be hide...until the row is updated...!!!
4) After update and delete total amount should be update..

Hi, it could be very useful, if you first wrote a simple HTML skeleton of the page even free of the scripts and features, but with the fully unique named items and/or with id. Than it could be much more simple to explain, what is the goal of the programming the features.

Here you are the page, and try to use it not for simple copy/pasting but for learning.

As I do not use MSIE I definitely cannot find out why Exploder does not show it.

tht was almost the perfect function....!!!! Thank u so much..!!
but sir i said only one text box from a row should be filled not both the fields...!!!
and there is one more field in which i m using dropdown and data coming from database...!!
another flaws i found tht when i edit a row..add button got disable and new lock button came in place of edit....but instead of edit if i delete the row... Add button still remain disable...!!!! i hpoe u got my point
but still its a gr8 function.....!!!!!
This javascript function i used for my work but it has lot of flaws..!!
