 We don't have to remove row elements, just "re-insert", they leave the old place automatically.
 
-Please note: our comparison function `(2)` returns `0` for equal table rows. That's handy for cases when we accidentally re-sort the table. E.g. if our users triggers such re-sorting. Returning `0` makes sure that same-named users won't get re-ordered, as opposed to a more simpler solution `valueA > valueB ? 1 : -1`.

 P.S. In our case, there's an explicit `<tbody>` in the table, but even if HTML table doesn't have `<tbody>`, the DOM structure always has it.
