Left most column in Generator.row not left-aligned properly

[fzl-22]

Hi, thanks for developed this cool library!

I got an issue when I use generator.row and generator.textLeftRight to print a row, the leftmost column is not left-aligned properly.

Here is my code:

      bytes += _generator.hr(ch: '=');
      final receiptNumber = label.receiptNumber;
      final shippingTotalWeight = '${label.shippingTotalWeight} kg';
      final shippingCost = Formatter.currency(label.shippingCost as int);
      bytes += _generator.row([
        PosColumn(
          text: 'Pengiriman',
          width: 6,
        ),
        PosColumn(
          text: receiptNumber,
          width: 6,
          styles: const PosStyles(align: PosAlign.right),
        ),
      ]);
      bytes += _generator.textLeftRight('Berat', shippingTotalWeight);
      bytes += _generator.textLeftRight('Ongkir', shippingCost);
      bytes += _generator.hr();bytes += _generator.hr(ch: '=');

Here is my Generator configuration:

  @preResolve
  Future<Generator> get generator async => Generator(PaperSize.mm80, await CapabilityProfile.load());

and I used CP1252 global code table.

Is there any way to fix this? Thank you!
