Invoice template

[Budrys]

Hello.

 

I want to make changes on my invoice template.

 

I have that code:

        <th class="product header-right small" width="{$layout.unit_price_tax_excl.width}%">{l s='Unit Price' pdf='true'} <br /> {l s='(Tax excl.)' pdf='true'}</th>
        <th class="product header-right small" width="{$layout.unit_price_tax_excl.width}%">{l s='Unit Price' pdf='true'} <br /> {l s='(Tax incl.)' pdf='true'}</th>
        <th class="product header small" width="{$layout.quantity.width}%">{l s='Qty' pdf='true'}</th>
        <th class="product header-right small" width="{$layout.total_tax_excl.width}%">{l s='Total' pdf='true'} <br /> {l s='(Tax incl.)' pdf='true'}</th>

 

Where could I change width of cells? I see that variables $layout.unit_price_tax_excl.width, $layout.quantity.width. Where are they setup?
