title: Set cell background using column and row index
body: <p>I am setting a cell value in phpexcel using below method <code>setCellValueByColumnAndRow()</code></p>
  
  <pre><code>$objPHPExcel-&gt;getActiveSheet()-&gt;setCellValueByColumnAndRow($col,$xlsRow,$plan);
  </code></pre>
  
  <p>Now my requirment is to set background color for this.</p>
  
  <p>I am not able to use this below method as I am aligned with rows and columns numbers.</p>
  
  <pre><code> $objPHPExcel-&gt;getActiveSheet()-&gt;getStyle("A1")-&gt;getFill()
      -&gt;setFillType(PHPExcel_Style_Fill::FILL_SOLID)
      -&gt;getStartColor()-&gt;setRGB($color);
  </code></pre>
  
  <p>I am searching a way to provide cols and rows as (2,3) not like ('A1:E1')</p>
  
  <p>Please suggest an alternative way to set background color using column and row numbers.</p>
