title: PHPExcel conditional formatting not quite right
body: <p>I'm trying to add a border to the bottom of all cells in every row after row 2 that satisfies this condition:</p>
  
  <pre><code>$objConditional1 = new PHPExcel_Style_Conditional();
  $objConditional1-&gt;setConditionType(PHPExcel_Style_Conditional::CONDITION_EXPRESSION)
                  -&gt;setOperatorType(PHPExcel_Style_Conditional::OPERATOR_EQUAL)
                  -&gt;addCondition('AND((B2&lt;&gt;B3),B2&lt;&gt;"")');
  $objConditional1-&gt;getStyle()-&gt;getBorders()-&gt;getBottom()-&gt;setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);  
  
  $conditionalStyles = $sheet-&gt;getStyle('B2')-&gt;getConditionalStyles();
  array_push($conditionalStyles, $objConditional1);    
  $sheet-&gt;getStyle('B2')-&gt;setConditionalStyles($conditionalStyles);
  
  $sheet-&gt;duplicateConditionalStyle(
  $sheet-&gt;getStyle('B2')-&gt;getConditionalStyles(),
      'B3:B9999'
  );
  </code></pre>
  
  <ol>
  <li>I'm not sure I understand how to add this condition to every single row and column after row 2...</li>
  <li>Second of all, the border is not being added as expected... In excel the formatting says (none)...</li>
  </ol>
  
  <p>Can I have some help with this?</p>
  
  <p>The goal is to look like this:
