PHPExcel setWidth(); - symfony

Question

Hi i'm using PhpExcel and Symfony2 , displaying excel files in HTML table.
My controller :
$filterSubset = new \PHPExcel_Reader_DefaultReadFilter('A','N');
$objReader = \PHPExcel_IOFactory::createReaderForFile($excel[0]);
$objReader->setReadFilter($filterSubset);
$objPHPExcel = $objReader->load($excel[0]);
$writer = \PHPExcel_IOFactory::createWriter($objPHPExcel, "HTML");
$writer->generateStyles();
$writer->generateSheetData();
return $this->render('MonextPerfclientBundle:Default:testexcel.html.twig', array(
'excelHtml'=>$writer,
'stylesExcel'=>$writer,
My ReadFilter class :
class PHPExcel_Reader_DefaultReadFilter implements PHPExcel_Reader_IReadFilter
{
public function __construct($fromColumn, $toColumn) {
$this->columns = array();
$toColumn++;
while ($fromColumn !== $toColumn) {
$this->columns[] = $fromColumn++;
}
}
public function readCell($column, $row, $worksheetName = '') {
// Read columns from 'A' to 'N'
if (in_array($column, $this->columns)) {
return true;
}
return false;
}
}
How can i set width of the 'E' column ?
Blanks columns still displaying..dont know why..
Why the width of columns are always different ?
Thanks #MarkBaker

Answer 1

To manage the width of columns cell you should setting the width in the controller.
.
$objPHPExcel->getActiveSheet()->getColumnDimension('E')->setWidth(40);
Blanks columns still displaying: You should manage the empty columns from the writer
The width of the olumns is depending on the length of data contained in first line.
