Add color to carrier column to order table in Prestashop administrative office

[Daniel_96]

Add the carriers column, and to the table 'ps_carrier_lang' add a column named 'color' as in the statuses, I want that color to be displayed.

'carrierdelay' => array( 'title' => $this->l('Envio'), 'type' => 'text', 'align' => 'text-center', 'class' => 'fixed-width-xl', 'color' => 'color', 'filter_key' => 'carrier_lang!delay', 'filter_type' => 'text', 'order_key' => 'carrier_lang!delay' ),

if I put 'color' => 'color',it will bring me the same color of the order status, but I want to define another type of color to the carriers

you have to add into list->_select also column 'color'.
Something like this ( colors and carriers set yourself -  of course)
 

...
,carrier_lang.delay, case when carrier_lang.id_carrier=1 then '#800000'
                          when carrier_lang.id_carrier=2 then '#008000' 
                          when carrier_lang.id_carrier=3 then '#000080'
                          else   '#808080' 
                     end as color

(I used carrier_lang alias, because do not know your alias for table ps_carrier)
