backpack for laravel column width

Is it possible to reduce columns width for certain columns in backpack crud for laravel, is there any attribute in add columns that allows that?

On the image displayed , i want to swap the 1s for glyphicon-ok, but i can't find a way to do it

public function setup(){

    $this->crud->setModel("App\ReporteParamEstacion");
    $this->crud->setRoute("admin/reporte_paramestacion");
    // $this->crud->setRouteName("crud.reportes.listado_importacion");
    $this->crud->setEntityNameStrings('parametro estacion', 'parametro estaciones');
    $this->crud->enableExportButtons();
    $this->crud->removeAllButtons();

     $this->crud->addColumn([
     'name' => 'nombre',
     'label' =>'Estacion',
     'type' => 'text'
    ]);

    $this->crud->addColumn([
     'name' => 'nombre_comuna',
     'label' =>'Comuna',
     'type' => 'text'
    ]);

    $this->crud->addColumn([
     'name' => 'MP10',
     'label' =>'MP10',
     'type' => 'text'


    ]);

    $this->crud->addColumn([
     'name' => 'MP25',
     'label' =>'MP25',
     'type' => 'text'

    ]);

    $this->crud->addColumn([
     'name' => 'SO2',
     'label' =>'SO2',
     'type' => 'text'
    ]);

    $this->crud->addColumn([
     'name' => 'NO2',
     'label' =>'NO2',
     'type' => 'text'
    ]); 

     $this->crud->addColumn([
     'name' => 'CO',
     'label' =>'CO',
     'type' => 'text'

    ]);  

    $this->crud->addColumn([
     'name' => 'O3',
     'label' =>'O3',
     'type' => 'text'
    ]);

    $this->crud->addColumn([
     'name' => 'BC',
     'label' =>'BC',
     'type' => 'text'
    ]);   

     $this->crud->addColumn([
     'name' => 'NOX',
     'label' =>'NOX',
     'type' => 'text'
    ]);  
 }

thanks in advance
