'o_column_sortable' : '')}"                             t-att-width="column.width()" t-att-colspan="column.colspan" >                         <t t-set="col" t-value="column.colspan or 1"/>                             <t t-if="column.tag !== 'button'"><t t-raw="column.heading()"/></t>                     </th>                     </t>                     <t t-if="col !== 0" t-set="col" t-value="col - 1"/>                 </t>                 <th t-if="options.deletable" class="o_list_record_delete"/>             </tr>         </thead>         <tfoot>             <tr>                 <td t-if="options.selectable"/>                 <td t-foreach="aggregate_columns" t-as="column" t-att-data-field="column.id" t-att-title="column.label">                 </td>                 <td t-if="options.deletable" class="o_list_record_delete"/>             </tr>         </tfoot>     </table>     </t> </div> </template>

add in __manifest__.py

... 'qweb': [         "static/src/xml/colspan.xml",     ], ...

that's it.

you can use colspan in field. in listview.

eg.

<tree>     <field name="any_field" colspan="2"/> </tree>

try it.

i hope work you.
