Add line numbers to the ListView view

There are three places that need to be modified:

1. var cell=[] In the View_list.js file in the Web module, add the following line after:

+        Cells.push (' <th class= ' oe_list_record_selector ' ></td> ');

In the Base.xml file in the 2.Web module, add the front header:

<th>    <t t-esc= "_t (' No ')"/> </th>

3. In the Base.xml file, the Tfooter tag is finally added <td/>, in order to correct the CSS deformation problem caused by a column added by the table header.

4. Finally, add the line number in the Listview.row template:

<th class= "Oe_list_record_selector" width= "1" >     <t t-raw= "view.records.indexOf (record) +1"/></th >

The final results are as follows:
