PHP生成excel(3)

这一节主要是设置背景颜色、边框、字体大小、表格宽度

效果图

代码如下

<?php
header("Content-Type:text/html;charset=utf-8");
require "./db.php";
require "./PHPExcel/PHPExcel.php";

//连接数据库
$db = Db::getInstance();

//实例化excel类
$objPHPExcel = new PHPExcel();
$objSheet = $objPHPExcel->getActiveSheet();//获取当前活动单元格

//设置水平居中
$objSheet->getDefaultStyle()->getAlignment()->setVertical(PHPExcel_Style_Alignment::VERTICAL_CENTER)->setHorizontal(PHPExcel_Style_Alignment::VERTICAL_CENTER);

//设置字体
$objSheet->getDefaultStyle()->getFont()->setName('微软雅黑')->setSize('13');
$objSheet->getStyle('A2:Z2')->getFont()->setSize('15')->setBold(True);
$objSheet->getStyle('A3:Z3')->getFont()->setSize('15')->setBold(True);

//设置背景颜色

//查询年级
$gradeInfo = $db->getResult("select `grade` from user group by grade order by grade asc");
//查询班级
$index = 0;
foreach ($gradeInfo as $k=>$val) {
    $gradeIndex = getCells($index * 2);
    $objSheet->setCellValue($gradeIndex.'2','高'.$val['grade']);
    $classInfo = $db->getResult("select distinct(class) from user where grade = ".$val['grade']." order by class");
    foreach ($classInfo as $j=>$vl) {
        $nameIndex = getCells($index * 2);//姓名列
        $scoreIndex = getCells($index * 2 + 1);//分数列

        $info = $db->getResult("select username,score from user where class=".$vl['class']." AND grade = ".$val['grade']." order by score desc");
        $objSheet->mergeCells($nameIndex.'3:'.$scoreIndex.'3');
        
        //设置班级背景颜色
        $objSheet->getStyle($nameIndex.'3:'.$scoreIndex.'3')->getFill()->setFillType(PHPExcel_Style_Fill::FILL_SOLID)->getStartColor()->setRGB('51e351');

        //设置班级边框
        $classBorderStyle = getBorderStyle('e351ca');
        $objSheet->getStyle($nameIndex.'3:'.$scoreIndex.'3')->applyFromArray($classBorderStyle);

        $objSheet->setCellValue($nameIndex.'3',$vl['class'].'班');
        
        //设置自动换行,注意需要用双引号换行符
        $objSheet->getStyle($nameIndex)->getAlignment()->setWrapText(true);
        $objSheet->setCellValue($nameIndex.'4',"姓名\n换行")->setCellValue($scoreIndex.'4','分数');
        
        //超长数字设置格式
        $objSheet->getStyle($scoreIndex)->getNumberFormat()->setFormatCode(PHPExcel_Style_NumberFormat::FORMAT_TEXT);
        $m = 5;
        foreach ($info as $v) {
            //$objSheet->setCellValue($nameIndex.$m,$v['username'])->setCellValue($scoreIndex.$m,$v['score']);//填充学生信息
            //->setValueExplicit('25', PHPExcel_Cell_DataType::TYPE_NUMERIC)
            
            //假如有超长数字
            $objSheet->setCellValue($nameIndex.$m,$v['username'])->setCellValueExplicit ($scoreIndex.$m,$v['score'].'123123123213123',PHPExcel_Cell_DataType::TYPE_STRING);
            $m++;
        }
        $index++;
    }
    $endGradeIndex = getCells(($index*2-1));//获得每个年级终止单元格
    //合并年级单元格
    $objSheet->mergeCells($gradeIndex.'2:'.$endGradeIndex.'2');//('A2:F2')
    $objSheet->getStyle($gradeIndex.'2:'.$endGradeIndex.'2')->getFill()->setFillType(PHPExcel_Style_Fill::FILL_SOLID)->getStartColor()->setRGB('e36951');
    //设置边框
    $gradeBorderStyle = getBorderStyle('e3df51');
    $objSheet->getStyle($gradeIndex.'2:'.$endGradeIndex.'2')->applyFromArray($gradeBorderStyle);
}


function getCells($index) {
    $arr = range('A','Z');
    return $arr[$index];
}

//获取不同的边框
function getBorderStyle($color) {
    $styleArray = array(
        'borders'=>array(
            'outline'=>array(
                'style'=>PHPExcel_Style_Border::BORDER_THICK,
                'color'=>array('rgb'=>$color)
            )
        )    
    );
    return $styleArray;
}

//按照指定格式生成excel文件
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');//生成excel 2007
$objWriter->save('style.xlsx');
