the indentation in your example is off, 24 should be indented one more right?

yes, it will probably involve javascript.
also rather than outputting table rows (belonging to a single table) think about
outputting as nested DIVs (or ULs.)

<div>
id : 10 most oranges come from florida
<div>
id : 16 ---- Re: most oranges come from florida (parentid 10)
<div>
id : 22 --------- Re: most oranges come from florida (parentid 16)
<div>
id : 24 -------------- Re: most oranges come from florida (parentid 22)
</div>
id : 28 ---- Re: most oranges come from florida (parentid 16)
</div>
</div>
</div>

such a setup would give you a very easy structure to grab/find parents using the DOM/javascript
