I am working on Magento 2 pdf invoice and trying to change layout of default invoice.As I have seen in default Magento pdf there are six column for displaying items in pdf
Products
SKU
Price
Qty
Tax
Subtotal
When I have checked in admin email template it is calling layout for displaying all items
{{layout area="frontend" handle="sales_email_order_invoice_items" invoice=$invoice order=$order}}
and in phtml file
vendor/magento/module-sales/view/frontend/templates/email/invoice/items.phtml
there are only three column
<thead>
<tr>
<th class="item-info">
<?= /* @escapeNotVerified */ __('Items'); ?>
</th>
<th class="item-qty">
<?= /* @escapeNotVerified */ __('Qty'); ?>
</th>
<th class="item-subtotal">
<?= /* @escapeNotVerified */ __('Subtotal'); ?>
</th>
</tr>
</thead>
I am not getting which file is exactly called when
{{layout area="frontend" handle="sales_email_order_invoice_items" invoice=$invoice order=$order}}
layout is loaded.Please help me if anybody know about it.
