如何让Perl的电子表格::WriteExcel使用VLOOKUP创建公式?

这是公式解析器和WriteExcel中某些公式类型的已知错误。你可以使用 store_formula() repeat_formula() 如下图所示:

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, A1:B10, 2, 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, $c, $r * 10 + $c);
    }
    $ws->write($r, 10, $r * 10);

    $ws->repeat_formula( $r, 11, $formula, undef, qr/^K1$/, 'K' . ($r +1) );
}

require 'rubygems'
require 'writeexcel'

wb = WriteExcel.new('fooruby.xls')
ws = wb.add_worksheet

formula = ws.store_formula('=VLOOKUP(K1, A1:B10, 2, FALSE)')

# Workaround for VLOOKUP bug in WriteExcel.
formula.map! {|f| f.sub(/_ref2d/, '_ref2dV') }

(0..9).each do |row|
  (0..4).each { |col| ws.write(row, col, row * 10 + col) }
  ws.write(row, 10, row * 10)
  ws.repeat_formula(row, 11, formula, nil, /^K1$/, "K#{row+1}" )
end

wb.close
