Are you talking about an HTML table, or some other output/layout
mechanism?

psuedo code from the top of my head

array[x,y]
pictures[]
counter =3D 0

for each array[x]
puts "<tr>"
for each array[x][y]
if ( pictures[ counter ] ) exists
puts "<td>" + image code + "</td>"
else
puts "<td></td>"
end
counter ++
end
puts "</tr>"
end


Ok, so that would basically get you there. a better way might exist,
but that is my first instinct.

Hope that helps

Josh

an array-less way to do it=20

pictures[]
counter =3D 0

5.times do
puts "<tr>"
5.times do
if ( pictures[ counter ] ) exists
puts "<td>" + image code + "</td>"
else
puts "<td></td>"
end
counter ++
end
puts "</tr>"
end

I think that is almost legal ruby code. I'm new to ruby, so I don't
know exactly. There is probably an even better way of doing this.=20
I'm really gray on ruby array handling

the help. any Ideas to make it better are welcome.

<table>

<% 5.times do %>
<tr>
<% 5.times do %>
<% if @systems[counter] %>
<td>
<table>
<tr>
<td><%=3D @systems[counter].company.name %></td>
<td><%=3D @systems[counter].model %></td>
<td><%=3D @systems[counter].sid %></td>
<td><%=3D @systems[counter].sm_img %></td>
</tr>
<% for price in @systems[counter].prices %>
<tr>
<td><%=3D price.price %></td>
<td><%=3D price.store_name %></td>
<td colspan=3D"2"></td>
</tr>
<% end %>
</table>
</td>
<% else %>
<td></td>
<% end %>
<% counter+=3D1 %>
<% end %>
</tr>
<% end %>=20
