Styling a custom column

Hi I have a custom column used in a table like this

    return $table
            ->columns([

                doclink::make(name: 'sp_file_id')
                ,

    return $table
            ->columns([

                doclink::make(name: 'sp_file_id')
                ,

I was assuming (wrongly

) that I could style it using the options available on text columns (e.g.

->badge

->badge

() ) but see that this is not valid.

Is there a standard way of enabling such styling options?

thanks
