Iterating through hash to line up dates correctly in a table

I have a simple table right now:

<table border=1>
  <tr>
    <td>OBS Number</td>
    <% for week in @week_endings%>
      <td><%=week.week_ending%></td>
    <%end%>
  </tr>
  <%@results.keys.each do |result| %>
    <tr>
      <td><%=result%></td>
      <% @results[result].each do |test| %>
        <td>Date: <%= test[0] %> - Hours: <%= test[1] %></td>
      <%end%>
    </tr>
  <%end%>
</table>

@week_endings contains dates that are applicable to my @results object
which is a nested hash of ID's containing dates which have associated
values.

After I setup my header which would look like:
OBS Number 01-04-2008 01-11-2008

I would like to iterate through my hash and where the data applicable,
place it in the table in the column containing the date it pertains to.

So a row would look like the following with the hash:
{"25",{"01-04-2008","5.0"},{"01-11-2008","10.0"}}
{"30",{"01-11-2008","10.0"}}

OBS Number 01-04-2008 01-11-2008
25 5.0 10.0
30 0.0 10.0

Where I'm building my rows using my hash with the following:
<%@results.keys.each do |result| %>
    <tr>
      <td><%=result%></td>
      <% @results[result].each do |test| %>
        <td>Date: <%= test[0] %> - Hours: <%= test[1] %></td>
      <%end%>
    </tr>
  <%end%>[/code]
I would think I could use my @week_endings object...

So something along the lines of
for result
  for week
    if result.week == week
     <td>value
    else
     <td>0
  end
end

An value for a day for given ID may not exist. So if could have a value
for the 11th but not the 4th so I need to skip by the 4th by putting a 0
in the field and move on to the 11th and insert that value.

But when I tried to code that my values weren't printing correctly.

Any thoughts would be appreciated, sorry if this comes off as confusing,
I tried to make it sound as simple as possible :slight_smile: I can always
elaborate if needed.

Thanks!
