我在CodeIgniter中扩展了一个处理PHPExcel的控制器。到目前为止，到目前为止，我还没有到Z列附近。到了之后，我受到了欢迎：

我已经编写了一些代码来生成AB-AZ BB-BZ列，但是 - 正如您在上面看到的那样 - PHPExcel没有它。

重申一下，在MySQL查询中添加更多列之前，一切都很顺利。
PHPExcel对我来说是个谜，所以任何帮助都会很精彩。
编辑6月11日，格林威治标准时间上午10:05
我对for（）循环进行了一些更改：
$a=1;
$p=1;
$r=0;
for ($s=65; $s<=90; $s++):
// Assign the letters of the alphabet.
for ($i=65; $i<=90; $i++):
if (chr($s) == "A"):
$array_column_indices[$a] = chr($i) . $p;
else:
$array_column_indices[$a] = chr($s-1) . chr($i) . $p;
endif;
$a++;
endfor;
$r++;
endfor;
虽然这已经解决了Z列问题，但我在电子表格中看到了奇怪的事情：
8 + 23 = 31行数据，这是正确的，但是为什么公式介于两者之间，还有差距？不知道。
所以，前进2步，后退1步。
答案 0 :(得分：3)
从堆栈转储中，您尝试获取单元格＆＃39; AA＆＃39;这不是有效的Excel单元格引用...它缺少行号：< / p>
PHPExcel_Worksheet->setCellValue('AA', 'Purchase Order ...')
请注意，有一个内置函数可以将列号转换为列名PHPExcel_Cell::stringFromColumnIndex()，或者您可以利用PHP增加字符串PERL样式的能力，或者（如果您更喜欢使用列的数字）使用工作表的setCellValueByColumnAndRow()方法
答案 1 :(得分：0)
最后，我的内容很接近，但需要进行一些调整：
$columns = ( ... count(of columns) ... );
$iterator_for_column_range=1;
// Assign the letters of the alphabet to the column ranges.
for ($x = 65; $x <= 90; $x++):
for ($y = 65; $y <= 90; $y++):
if (chr($x) == "A"):
$array_column_indices[$iterator_for_column_range] = chr($y);
else:
$array_column_indices[$iterator_for_column_range] = chr($x-1) . chr($y);
endif;
if ($iterator_for_column_range == $columns) break;
$iterator_for_column_range++;
endfor;
endfor;
此处，$columns变量会阻止列运行。
此外，在foreach循环中对迭代器变量进行了更改，以便它们只在每次传递时迭代一次：
$objPHPExcel->getActiveSheet()->setCellValue($array_column_indices[**$index_of_columns_for_column_name**] . **$index_of_range**, $arrayAttr['results']['config_database_tables']['tables'][$arrayAttr['results']['group']]['bookings'][$keys]);
完成！
