How To Add Row Number Or Serial No In Laravel Datatable

If you are using yajra laravel datatables

Just add ->addIndexColumn()

return DataTables::of($data)
->addIndexColumn()
->make(true);

In your javascript, you can set the first row as a serial number like this

columns: [
{ data: 'DT_RowIndex', name: 'DT_RowIndex', orderable: false, searchable: false },
{ data: 'name', name: 'name' },
{ data: 'action', name: 'action' }
]

use DT_Row_Index instead of DT_RowIndex for older yajra datatable version
