 var colCount=table.rows[0].cells.length;

alert(rowCount)

 for(var i=0;i<colCount;i++)
     {


 var newcell=row.insertCell(i);
 newcell.innerHTML=table.rows[0].cells[i].innerHTML;
 switch(newcell.childNodes[0].type)
     {case"text":newcell.childNodes[0].value="";
    // alert(2);
       var value = "" + "coll"+ j + i;
