PHP Excel阅读器:获取删除线/删除线值

我正在寻找一种方法来解析Excel表中单元格的删除线/删除线值,如果可能的话,使用PHP脚本。删除线或不包含简单文本值(没有公式或任何内容)的单元格。

我尝试添加以下内容:

function lineTrought($row,$col,$sheet=0) {
    return $this->fontProperty($row,$col,$sheet,'strikethrough');
}

            case SPREADSHEET_EXCEL_READER_TYPE_FONT:
                    $height = v($data,$pos+4);
                    $option = v($data,$pos+6);
                    $color = v($data,$pos+8);
                    $weight = v($data,$pos+10);
                    $under  = ord($data[$pos+14]);
                    **$strikethrough  = v($data,$pos+16);**
                    $font = "";
                    // Font name
                    $numchars = ord($data[$pos+18]);
                    if ((ord($data[$pos+19]) & 1) == 0){
                        $font = substr($data, $pos+20, $numchars);
                    } else {
                        $font = substr($data, $pos+20, $numchars*2);
                        $font =  $this->_encodeUTF16($font); 
                    }
                    $this->fontRecords[] = array(
                            'height' => $height / 20,
                            'italic' => !!($option & 2),
                            'color' => $color,
                            'under' => !($under==0),
                            'bold' => ($weight==700),
                            **'strikethrough'=>$strikethrough,**
                            'font' => $font,
                            'raw' => $this->dumpHexData($data, $pos+3, $length)
                            );
                    break;
