function main(){

var delImage=document.createElement("img"); 
delImage.setAttribute("alt","Edit"); 
delImage.setAttribute("src","drop.png");

var position=newRow.rowIndex;
var typeElem=document.createElement("a");
typeElem.setAttribute("name","delete");  
typeElem.setAttribute("href","#");
typeElem.appendChild(delImage);
typeElem.setAttribute('onclick',"delete(position)");

newRow.insertCell(lastCell).appendChild(typeElem);
