<para style="terp_default_8">[[repeatIn(o.order_line,'line')]][["" for l in range(10), 'line']]</para> <blockTable colWidths="20.0,100.0,150.0,80.0,50.0,20.0,60.0,50.0" style="Table_Order_Pur_line_Content"> <tr> <td> <para style="terp_default_9"> </para> </td> <td> <para style="terp_default_9">[[ ', '.join(map(lambda x: x.name, line.taxes_id)) ]]</para> </td> <td> <para style="terp_default_9">[[line.name]]</para> </td> <td> <para style="terp_default_Right_9">[[ formatLang(line.product_qty ) ]]</para> </td> <td> <para style="terp_default_Right_9">[[ formatLang(line.price_unit,digits=get_digits(dp='Product Price') ) ]]</para> </td> <td> <para style="terp_default_Right_9"> </para> </td> <td> <para style="terp_default_Right_9"> </para> </td> <td> <para style="terp_default_Right_9">[[ formatLang(line.price_subtotal,digits=get_digits(dp='Account'), currency_obj=o.pricelist_id.currency_id ) ]] </para> </td> </tr> </blockTable> </section>
