Create clone of table row and append to table in JavaScript

Question

In JavaScript, how can I add a row dynamically to a table? On a JavaScript event I want to create a similar row and append to the table.

Answer 1

tried all sorts of searches today, made use of sources : http://www.mredkj.com/tutorials/tablebasics3.html and http://www.mredkj.com/tutorials/tableaddcolumn.html

here's the result of my logic research, it's working now

    function addRow(id)
    { var x=document.getElementById(id).tBodies[0];  //get the table
      var node=t.rows[0].cloneNode(true);    //clone the previous node or row
      x.appendChild(node);   //add the node or row to the table
    }  

    function delRow(id)
    { var x=document.getElementById(id).tBodies[0]; //get the table
      x.deleteRow(1); //delete the last row
    }

NOTE1: my table contained a cell that had a textbox + a label in it per table row(tr).
NOTE2: in a row, there were multiple (td)'s that had a label + textbox
