Title: Sortable: Append a tr with td to the placeholder of tbody elements

When sorting tbody elements of a table the placeholder needs to have a tr with
td elements to be visible. The appended elements are created in the same way
as for the placeholder of a tr element; the first row of the sorted tbody is
used for that.
