PHPExcel

Question

Table 姓名：主题
我的预期输出

我的代码

<?php
    //dbconnection

    $q = "SELECT name FROM subject";
    $r = mysqli_query($dbc, $q);

    while($row = mysqli_fetch_array($r, MYSQLI_ASSOC))
    {
        $name[] = $row['name'];
    }

    $objPHPExcel = new PHPExcel();
    $objPHPExcel->setActiveSheetIndex(0);

    $headers = array('School Name');
    $objPHPExcel->getActiveSheet()->fromArray($headers, null, 'A1');
    $objPHPExcel->getActiveSheet()->fromArray($name, null, 'B1');

    $objPHPExcel->getActiveSheet()->mergeCells('B1:C1');
    $objPHPExcel->getActiveSheet()->mergeCells('D1:E1');
    $objPHPExcel->getActiveSheet()->mergeCells('F1:G1');
    $objPHPExcel->getActiveSheet()->mergeCells('H1:I1');
?>

我想为每个主题设置 colspan = 2。我不想写 4 行单独的代码。我尝试使用 for 循环如下：

$objWorksheet = $objPHPExcel->getActiveSheet();

$row = 1;
$highestColumn = $objWorksheet -> getHighestColumn();
$highestColumn++;

for($column = 'A'; $column != $highestColumn; $column++)
{
    if($column <= 'C')
    {
        //[HERE]
    }
}

我写完for循环后卡住了。我不知道如何控制列名和设置 colspan。有人可以帮助我吗？

在主题列表上循环执行此操作可能容易得多：

$objPHPExcel = new PHPExcel();
$objPHPExcel->setActiveSheetIndex(0);
$objPHPExcel->getActiveSheet()->setCellValue('A1', 'School Name');
$objPHPExcel->getActiveSheet()->mergeCells('A1:A2');

$column = 'B';
while($row = mysqli_fetch_array($r, MYSQLI_ASSOC))
{
    $objPHPExcel->getActiveSheet()->setCellValue($column.'1', $row['name']);
    $mergeRange = $column.'1:';
    $objPHPExcel->getActiveSheet()->setCellValue($column.'2', 'Student Name');
    $column++;
    $mergeRange .= $column.'1';
    $objPHPExcel->getActiveSheet()->setCellValue($column.'2', 'Grade');
    $objPHPExcel->getActiveSheet()->mergeCells($mergeRange);
    $column++;
}

PHPExcel - colspan 主题名称

PHPExcel - colspan the subject name
