I'm trying to change any fields of the table but only it change name of the "theads" but not the dinamic information. I'm trying to change "Description" field for the name of product in this case "product_id" but is not changing anything..

The original code in the report of "report_saleorder_document":

<...>

<thead>

<tr>

<th>Description</th>

<th>Taxes</th>

<th class="text-right">Quantity</th>

<th class="text-right">Unit Price</th>

<th groups="sale.group_discount_per_so_line">Disc.(%)</th>

<th class="text-right">Price</th>

</tr>

</thead>

<tbody class="sale_tbody">

<tr t-foreach="o.order_line" t-as="l">

<td class="text-right">

<span t-field="l.name"/>

</td>

<td>

<span t-esc="', '.join(map(lambda x: x.name, l.tax_id))"/>

</td>

<...>

------------------------------------------------------

And my code :

<...>

<thead>

<tr>

<th>Product Name</th>

<th>Taxes</th>

<th class="text-right">Quantity</th>

<th class="text-right">Unit Price</th>

<th groups="sale.group_discount_per_so_line">Disc.(%)</th>

<th class="text-right">Price</th>

</tr>

</thead>

<tbody class="sale_tbody">

<tr t-foreach="o.order_line" t-as="l">

<td class="text-right">

<span t-field="l.product_id.name"/> <!--This code I'm trying to change-->

</td>

<td>

<span t-esc="', '.join(map(lambda x: x.name, l.tax_id))"/>

</td>
