ok, in my example col 10's name = "foo",
to pick row 100, value in col10, do something like:
<a href="?id=100&grab=foo">get foo</a>
if(isset($id)&&isset($grab))
{
$q="select $grab from table where id='$id' limit 1";
$result=mysql_query($q);
}
that should work, it might have errors cause i just wrote it in here, but you get the idea
