我已经使用 PHPExcel 按行和列一起检查了这个 Merging cells in Excel by rows and columns但它只显示行添加但是我也对列应用了一些测试但没有一个工作。

此代码虽然成功创建了 excel 表，但 excel 中的输出抛出错误。

编辑

但是，如果删除 llop 并简单地说，这是可行的 -

$objPHPExcel->setActiveSheetIndex(0)->mergeCells('A1:B1');
$objPHPExcel->getActiveSheet()->setCellValue('A1', 'Swapnesh');

添加数据的主要代码 -

// Add some data
echo date('H:i:s') , " Add some data" , EOL;
$i = "A";
$j ="B";
for($num =1; $num <= 5; $num++ )
{
    $concat =  "{$i}1:{$j}1";
    $objPHPExcel->setActiveSheetIndex(0)->mergeCells($concat);
    $i++;$j++;
} 
$objPHPExcel->getActiveSheet()->setCellValue('A1', 'Swapnesh');

我的整个代码 -

<?php
error_reporting(E_ALL);
ini_set('display_errors', TRUE);
ini_set('display_startup_errors', TRUE);

define('EOL',(PHP_SAPI == 'cli') ? PHP_EOL : '<br />');

date_default_timezone_set('Asia/Calcutta');

我自己想出了解决方案-

实际上，在列合并的情况下，我们实际上不需要迭代。假设我想从 column 合并A1到E1.

因此，可以很容易地通过以下方式完成，而不是逐个循环地完成 -

$objPHPExcel->setActiveSheetIndex(0)->mergeCells('A1:E1');

所以在我的情况下，我首先需要找到最后一个元素和第一个元素，然后简单地放入 mergeCells() 方法以使其工作。

当您尝试在循环中合并两个单元格时会发生此问题。原因不是您正在迭代的循环，而是您正在传递的列名。如果您传递了错误的列名，那么您的 excel 将不会产生正确的输出。

以下是获取下一个 excel 列的简单程序，这样我们就不会遇到此类问题。

/* manage excel index */
function getColumn($prevColumn){
    if(strlen($prevColumn)==1&&$prevColumn!="Z")
    { $prevColumn++;return $prevColumn; }

    $colum = '';
    $list = str_split($prevColumn);

    if(count($list)==1&&$list[0]=='Z')
    {
        $list[0] = "A";
        $list[1] = "A";
    }
    else if(count($list)==2&&$list[1]!='Z')
    {
        $list[1]++;
}
    else if(count($list)==2&&$list[1]=='Z')
    {
        $list[0] = "B";
        $list[1] = "A";
}
return implode('',$list);
}

## us this like below

$column = "A";
$row = 1;
foreach($array_to_print as $details)
{

$column = getColumn($column); // product next column B
$Excelobj->getActiveSheet()->setCellValue($column.$row, $details);
$column = getColumn($column);// product next column C
$Excelobj->setActiveSheetIndex(0)->mergeCells($from_cell.':'.$to_cell);// now this will  work till A-ZZ column in excel
}
