PHPExcel 生成excel统计表格

db.php为数据库操作类, $config为数据库配置,PHPExcel版本为PHPExcel_1.8.0,  php代码:

$dir = dirname(__FILE__);
require $dir . "/PHPExcel/db.php";
require $dir . "/PHPExcel/PHPExcel.php";
$object = new PHPExcel();
$db = new db($config);

$objSheet = $object->getActiveSheet();

//文字居中和文字设置
$objSheet->getDefaultStyle()->getAlignment()->setVertical(PHPExcel_Style_Alignment::VERTICAL_CENTER)->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
$objSheet->getDefaultStyle()->getFont()->setName("微软雅黑")->setSize(14);
$objSheet->getStyle("A2:X2")->getFont()->setSize(20)->setBold(TRUE);
$objSheet->getStyle("A3:X3")->getFont()->setSize(16)->setBold(TRUE);

//设置行高
$objSheet->getRowDimension(2)->setRowHeight(35);
$objSheet->getRowDimension(3)->setRowHeight(25);
$objSheet->getRowDimension(4)->setRowHeight(20);

//填充颜色
$objSheet->getStyle("A2:X2")->getFill()->setFillType(PHPExcel_Style_Fill::FILL_SOLID)->getStartColor()->setRGB('ffff00');
$objSheet->getStyle("A3:X3")->getFill()->setFillType(PHPExcel_Style_Fill::FILL_SOLID)->getStartColor()->setRGB('ff0000');

//sheet名长
$objSheet->setTitle("成绩表");

//查询所有的年级
$i = 0;
$data_g = $db->getAllGrade();
foreach($data_g as $g_k=>$g_v) {

    //查询每个年级有几个班
    $data_c = $db->getAllClassBYGrade($g_v['grade']);

    //获取年级所在单元格并填充单元格
    $gradeIndex = $i*2;
    $grade = getCells($gradeIndex);
    $objSheet->setCellValue($grade."2", $g_v['grade']."年级");
