I am using Rails 2.1 to output tables from a database. But the output includes lots of extra lines and tabs. I am using a while loop with lots of nested if statements. I am also wrapping all of my non-output lines in <%- code -%>. Any idea what might be happening and a solution? Thanks,

ex:

<tr>



          <td>Some data</td>


                           <td>more data</td>
