如何让Perl的Spreadsheet :: WriteExcel用VLOOKUP创建公式？

我在 Spreadsheet::WriteExcel和使用VLOOKUP的公式方面遇到了困难.以下测试脚本使用一些数据填充工作表,并尝试创建VLOOKUP公式.当我打开生成的Excel文件时,公式结果显示为#VALUE！.如果我手动编辑任何包含公式的单元格(按F2然后只输入ENTER而不更改任何内容),我可以让Excel正确评估公式.知道出了什么问题吗？

对于它的价值,如果我在OpenOffice中打开相同的文件,公式工作正常.

use strict;
use warnings;
use Spreadsheet::WriteExcel;

my $wb = Spreadsheet::WriteExcel->new('foo.xls');
my $ws = $wb->add_worksheet;

for my $r (0 .. 9){
    for my $c (0 .. 4){
        $ws->write($r,$c,$r * 10 + $c);
    }
    $ws->write($r,10,$r * 10);
    my $formula = sprintf('=VLOOKUP(K%s,A1:B10,2,FALSE)',$r + 1);
    $ws->write( $r,11,$formula );
    # $ws->write_formula( $r,$formula ); # Does not help either.
}

版本信息：

> Excel 2007 SP2.

use strict;
use warnings;
use Spreadsheet::WriteExcel;

my $wb = Spreadsheet::WriteExcel->new('foo.xls');
my $ws = $wb->add_worksheet;

my $formula = $ws->store_formula('=VLOOKUP(K1,FALSE)');

# Workaround for VLOOKUP bug in WriteExcel.
@$formula = map {s/_ref2d/_ref2dV/;$_} @$formula;

for my $r (0 .. 9){
    for my $c (0 .. 4){
        $ws->write($r,$r * 10);

    $ws->repeat_formula( $r,$formula,undef,qr/^K1$/,'K' . ($r +1) );
}
