如何使PHPExcel自动创建列宽度，我不喜欢手动进入并拉伸列。我已经看过其他的例子，但对我来说都没有。这是我的代码：

$objPHPExcel->setActiveSheetIndex(0);

$objPHPExcel->getActiveSheet()->setCellValue('A1', "Company Name");

$objPHPExcel->getActiveSheet()->setCellValue('B1', "Company Type");

$objPHPExcel->getActiveSheet()->setCellValue('C1', "First Name");

$objPHPExcel->getActiveSheet()->setCellValue('D1', "Last Name");

$objPHPExcel->getActiveSheet()->setCellValue('E1', "Position");

$objPHPExcel->getActiveSheet()->setCellValue('F1', "Email");

// Set outline levels

$objPHPExcel->getActiveSheet()->getColumnDimension('E')->setOutlineLevel(1)

->setVisible(false)

->setCollapsed(true);

// Freeze panes

$objPHPExcel->getActiveSheet()->freezePane('A2');

// Rows to repeat at top

$objPHPExcel->getActiveSheet()->getPageSetup()->setRowsToRepeatAtTopByStartAndEnd(1, 1);

try {

$stmt3 = $DB->prepare('SELECT * FROM companies C INNER JOIN personalInfo PI ON C.CompanyName = PI.Company_id');

$stmt3->execute();

} catch(PDOException $e) {

echo $e->getMessage();

}

$info3 = $stmt3->fetchAll();

$i = 2;

foreach($info3 as $info) {

$objPHPExcel->getActiveSheet()->setCellValue('A' . $i, $info['CompanyName'])

->setCellValue('B' . $i, $info['CompanyType'])

->setCellValue('C' . $i, $info['firstName'])

->setCellValue('D' . $i, $info['lastName'])

->setCellValue('E' . $i, $info['position'])

->setCellValue('F' . $i, $info['email']);

$i++;

}

// Set active sheet index to the first sheet, so Excel opens this as the first sheet

$objPHPExcel->setActiveSheetIndex(0);

// Save Excel 2007 file

$callStartTime = microtime(true);

$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');

$objWriter->save(str_replace('.php', '.xlsx', __FILE__));

$callEndTime = microtime(true);

$callTime = $callEndTime - $callStartTime;

echo "Excel file has been created click HERE to view it.";
