How to add new field to product list table?

It's very simple html / smarty task. Open file adminXXXX/themes/default/template/controllers/orders/helpers/view/view.tpl where adminXXXX is your admin directory. You can find there table with fields definition, you can find it near 886 line (prestashop 1.6). it looks like:

                                                 <table class="table" id="orderProducts">
							<thead>
								<tr>
									<th></th>
									<th><span class="title_box ">{l s='Product'}</span></th>
									<th>
										<span class="title_box ">{l s='Unit Price'}</span>
										<small class="text-muted">{$smarty.capture.TaxMethod}</small>
									</th>
									<th class="text-center"><span class="title_box ">{l s='Qty'}</span></th>
									{if $display_warehouse}<th><span class="title_box ">{l s='Warehouse'}</span></th>{/if}
									{if ($order->hasBeenPaid())}<th class="text-center"><span class="title_box ">{l s='Refunded'}</span></th>{/if}
									{if ($order->hasBeenDelivered() || $order->hasProductReturned())}
										<th class="text-center"><span class="title_box ">{l s='Returned'}</span></th>
									{/if}
									{if $stock_management}<th class="text-center"><span class="title_box ">{l s='Available quantity'}</span></th>{/if}
									<th>
										<span class="title_box ">{l s='Total'}</span>
										<small class="text-muted">{$smarty.capture.TaxMethod}</small>
									</th>
									<th style="display: none;" class="add_product_fields"></th>
									<th style="display: none;" class="edit_product_fields"></th>
									<th style="display: none;" class="standard_refund_fields">
										<i class="icon-minus-sign"></i>
										{if ($order->hasBeenDelivered() || $order->hasBeenShipped())}
											{l s='Return'}
										{elseif ($order->hasBeenPaid())}
											{l s='Refund'}
										{else}
											{l s='Cancel'}
										{/if}
									</th>
									<th style="display:none" class="partial_refund_fields">
										<span class="title_box ">{l s='Partial refund'}</span>
									</th>
									{if !$order->hasBeenDelivered()}
									<th></th>
									{/if}
								</tr>
							</thead>
							<tbody>
							{foreach from=$products item=product key=k}
								{* Include customized datas partial *}
								{include file='controllers/orders/_customized_data.tpl'}
								{* Include product line partial *}
								{include file='controllers/orders/_product_line.tpl'}
							{/foreach}
							{if $can_edit}
								{include file='controllers/orders/_new_product.tpl'}
							{/if}
							</tbody>
						</table>

we just simple have to add there new field in that way:

<th><span class="title_box">{l s='Manufacturer'}</span></th>

So, we just simple have to modify whole table code to: (I highlighted new line)

<table class="table" id="orderProducts">
							<thead>
								<tr>
									<th></th>
									<th><span class="title_box ">{l s='Product'}</span></th>
                                    <th><span class="title_box">{l s='Manufacturer'}</span></th>
									<th>
										<span class="title_box ">{l s='Unit Price'}</span>
										<small class="text-muted">{$smarty.capture.TaxMethod}</small>
									</th>
									<th class="text-center"><span class="title_box ">{l s='Qty'}</span></th>
									{if $display_warehouse}<th><span class="title_box ">{l s='Warehouse'}</span></th>{/if}
									{if ($order->hasBeenPaid())}<th class="text-center"><span class="title_box ">{l s='Refunded'}</span></th>{/if}
									{if ($order->hasBeenDelivered() || $order->hasProductReturned())}
										<th class="text-center"><span class="title_box ">{l s='Returned'}</span></th>
									{/if}
									{if $stock_management}<th class="text-center"><span class="title_box ">{l s='Available quantity'}</span></th>{/if}
									<th>
										<span class="title_box ">{l s='Total'}</span>
										<small class="text-muted">{$smarty.capture.TaxMethod}</small>
									</th>
									<th style="display: none;" class="add_product_fields"></th>
									<th style="display: none;" class="edit_product_fields"></th>
									<th style="display: none;" class="standard_refund_fields">
										<i class="icon-minus-sign"></i>
										{if ($order->hasBeenDelivered() || $order->hasBeenShipped())}
											{l s='Return'}
										{elseif ($order->hasBeenPaid())}
											{l s='Refund'}
										{else}
											{l s='Cancel'}
										{/if}
									</th>
									<th style="display:none" class="partial_refund_fields">
										<span class="title_box ">{l s='Partial refund'}</span>
									</th>
									{if !$order->hasBeenDelivered()}
									<th></th>
									{/if}
								</tr>
							</thead>
							<tbody>
							{foreach from=$products item=product key=k}
								{* Include customized datas partial *}
								{include file='controllers/orders/_customized_data.tpl'}
								{* Include product line partial *}
								{include file='controllers/orders/_product_line.tpl'}
							{/foreach}
							{if $can_edit}
								{include file='controllers/orders/_new_product.tpl'}
							{/if}

How to display manufacturer name in new filed?

in this case we have to modify different file: adminXXXX/themes/default/template/controllers/orders/_product_line.tpl. We have there functions to display product information associated with order. So, we have to add there new <td></td> field. By default code looks like: (you can find it near line 34)

<tr class="product-line-row">
	<td>{if isset($product.image) && $product.image->id}{$product.image_tag}{/if}</td>
	<td>
		<a href="index.php?controller=adminproducts&amp;id_product={$product['product_id']}&amp;updateproduct&amp;token={getAdminToken tab='AdminProducts'}">
			<span class="productName">{$product['product_name']}</span><br />
			{if $product.product_reference}{l s='Reference number:'} {$product.product_reference}<br />{/if}
			{if $product.product_supplier_reference}{l s='Supplier reference:'} {$product.product_supplier_reference}{/if}
		</a>
	</td>

Right after this code add field with manufacturer information, we will use Manufacurer class function getNameById (function returns manufacturer name), code below:

    <td>
    {Manufacturer::getnamebyid($product.id_manufacturer)}
    </td>

And that's all. after page refresh you should see there new field with manufacturer name. If you dont see it, make sure that you recompiled theme and cleared shop cache.
