I'm trying to port a very small portion of a php script i used to have.
the concept is quite easy, but I dont see how to accomplish it at zope.
let' see if anyone can understand this php code and tell me which function
at zope may I use for it:
print "<table>";
print "<tr>";
while ($item = current($array))
{
   for ($n=0 ;$n<3;$n++)
   {
      print "<td>$item</td>";
      next($array);
   }
   print "</tr>";
}
print "</table>";
what this code does is to print all the contents of an array in a table of 3
columns, using a cell for each element. I'm trying to do this same thing but
using a <dtml-in expr="objectValues('Folder')"> instead of the array.
Can someone provide a dtml sample on how to do this?
I'd do it as a PythonMethod or PythonScript:

output = '<table>\n'
column = 1

for item in array:
        if column == 1:
                output = output + '<tr>\n'

        output = output + '<td>%s</td>\n' % item

        if column == max_column:
                output = output + '</tr>\n'
                column = 1:
        else:
                column = column + 1

output = output + '</table>\n'

return output

This code is written off the top of my head, so I don't know if it works.
I do know that it won't do too well when the number of elements in the
array isn't a muliple of max_column; I'll leave that as an exercise for
the reader :-)
