Question

我很难设法让Spreadsheet :: WriteExcel的write_row / write_col打印excel表中的行。

我有这种工作方法将它们打印为文本文件。但是将它们作为行/列写入excel表是我失败的地方。我的$ com_sam是这样的。它是一个多级哈希，它包含所有匹配的样本及其作为键的百分比以及它们与每个样本匹配的所有其他详细信息。（X3，X32，E32_P，E32_PL是样本）



    'X3' => {
                                 '100.00' => [
                                               {
                                                 'NoofCalls' => 30,
                                                 'percent' => '100.00',
                                                 'NoofNs' => 0,
                                                 'match' => 30,
                                                 'sample' => 'X3'
                                               },
                                               {
                                                 'NoofCalls' => 30,
                                                 'percent' => '100.00',
                                                 'NoofNs' => 0,
                                                 'match' => 30,
                                                 'sample' => 'X32'
                                               },
                                               {
                                                 'NoofCalls' => 30,
                                                 'percent' => '100.00',
                                                 'NoofNs' => 0,
                                                 'match' => 30,
                                                 'sample' => 'E32_P'
                                               },
                                               {
                                                 'NoofCalls' => 30,
                                                 'percent' => '100.00',
                                                 'NoofNs' => 0,
                                                 'match' => 30,
                                                 'sample' => 'E32_PL'

                                               },

这是我的代码尝试使用WriteExcel将它们打印到excel。


    foreach my $percent ( sort { $b  $a } keys %{ $com_sam->{ $s1 } } ){
    249 
    250     my $match_samples = $com_sam->{ $s1 }->{ $percent };
    251 
    252     foreach my $matSam( @ { $match_samples } ){
    253       if( ( $s1 ne $matSam->{ sample } ) and ($matSam->{ percent } >= $top_percent) ) {
    254 
    255           next if compare($s1, $matSam->{sample});
    256 #         print  "****,$s1,$matSam->{ sample },$matSam->{ percent },$top,$top_percent,$matSam->{ NoofCalls },$matSam->{ match }, $matSam->{ NoofNs },****\n" ; 
    257           push @$log_array,($s1,$matSam->{ sample },$matSam->{ percent },$top,$top_percent,$matSam->{ NoofCalls },$matSam->{ match }, $matSam->{ NoofNs } );
    258           push @$array_ref_log, @$log_array;
    259           for my $col (0 ..7) {
    260 
    261             for my $row (1 .. scalar(@sam2com) ) {
    262 
    263                 $worksheet->write_row($row,$col,$array_ref_log);#Wat I get with this is just a single sample compared rather than all the sample. 

    264             }
    265 
    266 
    267           }
    268       }else{ 
    269 
    270         my $total_calls = $matSam->{ NoofCalls } + $matSam->{ NoofNs };
    271 
    272         my $l = sprintf "%s, %s, %0.2f, %s, %0.2f,%s,%s,%s", $s1, $matSam->{ sample }, $matSam->{ percent }, $top, $top_percent,$matSam->{ NoofCalls },$matSam->{ match }, $matSam->{ NoofNs } ;
    273 
    274         if( $total_calls ==  97 ) {
    275 
    276 #         print "$l\n" if ( $matSam->{ NoofNs } { NoofNs } sample
    287   }#end of percentage foreach loop

我希望看到像这样的结果


    X3,X3,100.00,X3,100.00,30,30, 0
    X3,X32_P,100.00,X3,100.00,30,30, 0
    X3,E32,100.00,X3,100.00,30,30, 0

但我在excel中得到这样的结果。（当然不是以逗号分隔:)）


    X3,X32,100.00,X3,100.00,30,30, 0,X3,X32_P,100.00,X3,100.00,30,30, 0,X3,E32,100.00,X3,100.00,30,30, 0

如何处理write_row / write_col的array_ref？提前致谢

Answer 1

很难从这段代码中分辨出问题是什么，但我可以提出一些建议。

第一个是不使用write_row()，因为它只是语法糖，而是使用您自己的for()循环和write()。

第二个是，如果你使用write_row()，请确保你清楚它与嵌套数组引用的行为方式。研究write_row documentation中的示例，看它是否符合您的期望。可能需要write_col()代替。

最后，这不是一个Spreadsheet::WriteExcel问题，而是与数据结构的处理有关。您可以使用简单的print()语句替换write *函数，直到您确定已捕获需要捕获的数据，然后添加所需的WriteExcel函数。

Answer 2

要在XLSX文件中写入大量数据，可以使用Excel_Writer_XLSX perl mudule。在XLSX中迭代和打印数据非常简单，如下所示

     my@records = ( [ "10001", "1/5/2011", "Jan", "Midwest", "Ami", "Binder", "94", "20" ],
                     [ "10002", "1/13/2011", "May", "West Coast", "Stevenson", "Pencil", "3", "275" ],
                     [ "10051", "2/24/2011", "Nov", "Midwest", "Jones", "Desk", "35", "4.99" ],
                     [ "10086", "3/7/2011", "Apr", "New England", "Andrews", "Pen Set", "16", "20" ],
                     [ "10450", "4/10/2011", "Dec", "Midwest", "Adams", "Ball", "20", "57.2" ],
                     [ "16001", "7/19/2011", "Mar", "West Coast", "Thompson", "Note Book", "28", "33.5" ],
                     [ "19565", "6/23/2011", "Jul", "Midwest", "Dwyer", "Scale", "15", "16" ],
                     [ "20048", "6/15/2011", "Oct", "Midwest", "Morgan", "Stickers", "96", "12" ],
                     [ "50962", "2/7/2011", "Feb", "New England", "Howard", "Clips", "52", "5.5" ],);

my $workbook        = Excel::Writer::XLSX->new($outputFile);
$workbook->set_optimization();
my $worksheet   = $workbook->add_worksheet('Test'); 
my $row         = 0;
my $col         = 0;
foreach my $record (@records){
        $row++;
        $col = 0;

        foreach my $data (@{$record}){
            $worksheet->write($row,$col,$data);     
            $col++;
        }
    }
