Question

是否可以使用box / spout冻结电子表格的第一行（冻结窗格）？

使用PHPexcel我喜欢这样：

$objPHPExcel=new PHPExcel();
$ActiveSheet=$objPHPExcel->getActiveSheet();
$ActiveSheet->freezePane('A2');

无法使用PHPexcel，因为我正在使用大文件。

Answer 1

用Spout冻结窗格是不可能的。但你总是可以分叉回购并实现这个功能：）

class SpoutHelper {

    private $rawHeadersArray = []; //Local array to hold the Raw Headers for performance

    public function getFormattedHeaders($sheet) {
        if (empty($this->formattedHeadersArray)) {

                    $this->formattedHeadersArray[$key] = strtolower(str_replace(' ' , '_', trim($value)));
                }
                /**
                 * Add more rules here as needed
                 */
            }
        } else {
            /**
             * Return from local cache
             */

        return $this->formattedHeadersArray;
    }
    /**
     * Return row with Raw Headers
     */
    public function rowWithRawHeaders($rowArray) {
        return $this->returnRowWithHeaderAsKeys($this->rawHeadersArray, $rowArray);
    }
    /**

     */
    public function rowWithFormattedHeaders($rowArray) {
        return $this->returnRowWithHeaderAsKeys($this->formattedHeadersArray, $rowArray);
    }
    /**
     * Set the headers to keys and row as values
     */
    private function returnRowWithHeaderAsKeys($headers, $rowArray) {

        $headerColCount = count($headers);
        $rowColCount = count($rowArray);
        $colCountDiff = $headerColCount - $rowColCount;
        if ($colCountDiff > 0) {
            //Pad the rowArray with empty values 
            $rowArray = array_pad($rowArray, $headerColCount, '');
        }
        return array_combine($headers, $rowArray);
    }
    /**
     * Flush local caches before each sheet
     */
    public function flushHeaders() {
        $this->formattedHeadersArray = [];
        $this->rawHeadersArray = [];
    }

}

然后在您的主文件中可以执行以下操作：

$reader = ReaderEntityFactory::createReaderFromFile($filePath);
$reader->open($filePath);

/**
 * Now get the data
 */
foreach ($reader->getSheetIterator() as $sheet) {

    $spoutHelper = new SpoutHelper($sheet, 1); //Initialize SpoutHelper with the current Sheet and the row number which contains the header

        foreach ($sheet->getRowIterator() as $key => $row) {

            if ($key == 1) {
                //echo "Skipping Headers row";
                continue;
            }

            //Get the indexed array with col name as key and col val as value`
            $rowWithHeaderKeys = $spoutHelper->rowWithFormattedHeaders($row->toArray());                   
      }
 }

Answer 3

发现了添加此功能的黑客。

在Spout \ Writer \ XLSX \ Manager \ WorksheetManager.php中：函数startSheet

此行之后

.encodeSerializable(Body.serializer(), body)

添加此行

fwrite($sheetFilePointer, self::SHEET_XML_FILE_HEADER);
