rowOne is a reference to a row element, the above will move it from
wherever it is to be the last row.

Yes, once you've added the row referenced by rowOne to the table, you
can create another row and assign a reference to it. In this case,
consider cloning rowOne:
tbody.appendChild(rowOne.cloneNode(true));
That will clone rowOne and add it as the last row of the table, be
mindful of duplicated IDs and other attributes that you might want to
be unique.
You might find it quicker and simpler to add rows using insertRow, it
creates and adds the row in one step, e.g. from your code:
var rowOne = tbody.insertRow(-1); // rowOne is created & appended
rowOne.appendChild( Builder.node(...) );
/* add row 2 */
tbody.appendChild(rowOne.cloneNode(true));
It also removes the requirement to create a tbody element if you only
have one, just use insertRow(-1) with the table element. You might
still want to use an explicit tbody if you have multiple
tableSectionElements and need to specify which one to add the rows to.
