[PHP][好文] 使用 PHPExcel 產生 xlsx 的檔案 (Export Html contents to Excel file using PHPExcel)

php_export_html_to_excel_via_phpexcel

補充一些進階應用：

$objPHPExcel = $objWriter->getPHPExcel();

//抓最大的行列
$str_col = $objPHPExcel->setActiveSheetIndex(0)->getHighestColumn();  //最大列號 eg.J
$str_row = $objPHPExcel->setActiveSheetIndex(0)->getHighestRow();  //最大行數 eg.21
$str_dim = $objPHPExcel->setActiveSheetIndex(0)->calculateWorksheetDimension();  //最大行列 eg.A1:J21

//自動欄寬
foreach(range('A',$str_col) as $columnID) {
  $objPHPExcel->getActiveSheet()->getColumnDimension($columnID)->setAutoSize(true);
}

//自動換行
$objPHPExcel->getActiveSheet()->getStyle($str_dim)->getAlignment()->setWrapText(true);

$objWriter->save($excelFile);
