Thank you both.  I kind of like the above approach, it does not seem
to solve the problem.
Here's more detail:

function addNew(i) {
 var newF =3D do***ent.getElementById('tbl');
 var a =3D [];
 a[i] =3D newF.insertRow();
 //  ...
 }

The above code failed.  A related question, how to increment a value?
The following won't work
 // the i value is param for a function like the above one, not be
concerned
 var rowCount =3D 1;
 rowCount =3D eval(rowCount + i);
 alert (rowCount);
