How to show separate fields in invoce?

Hi, there!
First of all you’ve made great plugin! Thank you!

But I have one question.

I’ve changed template for my own purposses like this:
Product | SKU | Color | Size | Quantity | Price per 1 item | Price for all items
———————————————————————————

Everething fine exept separate values for Color and Size.

If I’m using this code:

<td class="COLOR"><?php if (!empty($item['product'])) : ?>
			<?php $wpo_wcpdf->product_attribute('color', $item['product']); ?>

			<?php endif; ?></td>

Invoice prints all available variations for this product.

If I’m using this:
`<?php echo $item[‘meta’]; ?>’ I see choosen type of color and size but in one column.

Please help! How to separate this values and see only choosen options for one column?
