Dom setAttribute ondblclick & ID for Table row/cell

Hi,

How do I add an onDblClick event for each table TR being created & how do I add an ID for each Cell being created.

function addRow(val1,val2)
{
tabBody = document.getElementsByTagName("TBODY").item(3);
row = document.createElement("TR");
cell1 = document.createElement("TD");
cell2 = document.createElement("TD");
textnode1 = document.createTextNode(val1);
textnode2 = document.createTextNode(val2);
cell1.appendChild(textnode2);
cell2.appendChild(textnode1);
row.appendChild(cell1);
row.appendChild(cell2);
tabBody.appendChild(row);
}
