<% all.each do |row| %>
<tr>
  <td><%= row[0] %></td>
  <td><%= row[1] %></td>
  <td>etc</td>
</tr>
<% end %>

You are currently using row.join("sep") which joins all the array 
elements together.

If 'all' is an Array of Arrays, then the total number of rows is <%= 
all.size %>

Note that you should be HTML-escaping the values before inserting them 
into the page (consider what happens if row[0] contains < or &).

To keep the templates simple you could define a helper method 'h' like 
Rails does. Then you'd use it like this:

  <td><%=h row[0] %></td>
