PHPExcel cell style formatting error on a non-object - php

Question

I'm trying to format cell in my xls output sheet but when I'm trying to use
$xls->getActiveSheet()->getStyle('A1')->getFont()->getColor()->setRGB(PHPExcel_Style_Color::COLOR_WHITE);
or any other method with getStyle() I'm getting this error:
( ! ) Fatal error: Call to a member function getNumberFormat() on a non-object in "..."/Worksheet.php in line 755
Other getActiveSheet() methods like setTitle() or getColumnDimension() are working fine. I'm using Excel5 writer, but when I tried Excel2007 I got the same error. Anyone know what might be the problem? Thanks in advance.
When I comment out the column width loop I don't get the error, but the style applying still doesn't work. Column width loop works perfectly without style applying code.

You can try this method to add style to your PHPExcel.
First create a array with the styles.
Something like this
$color = array(
'fill' => array(
'type' => PHPExcel_Style_Fill::FILL_SOLID,
'color' => array('rgb' => 'A5A5A5')
),
'borders' => array(
'allborders' => array(
'style' => PHPExcel_Style_Border::BORDER_THIN
)
),
'alignment' => array(
'horizontal' => PHPExcel_Style_Alignment::HORIZONTAL_CENTER,
)
);
After creating the array you have to apply the styles to your object.
Something like this.
$xls->getActiveSheet()->getStyle('A1:A10')->applyFromArray($color);
