The HTML specification says that a table has one or more tbody
elements, each of which contains one or more tr elements. You can't
nest a tbody in a tbody, or a tr in a tr.
So, if you need to add a row, you can either add it to an existing
tbody, or add a new tbody (containing it) to the table.
But if you need to replace one row in a tbody,
*either* you can work on the tbody, in which case you will have to
remove the existing tr and insert the new one yourself,
*or* you operate on the tr, and update its contents (with a list of th/
td elements, not with a tr).
What I would do is to make sure that each row (including each added
row) has a unique id, and then use Ajax.Updater(<id of row>, ... )
and make sure the updating code in this case is a list of cells, not a
tr.
