    // Rename thumbnail column
    $earnings_columns['thumbnail'] = __( 'Image', 'gamipress' );
    // Remove the points column
    unset( $earnings_columns['points'] );
    return $earnings_columns;
}
add_filter( 'gamipress_earnings_columns', 'my_prefix_gamipress_earnings_columns', 10, 2 );

Adding a custom column

function my_prefix_gamipress_earnings_new_column( $earnings_columns, $template_args ) {
    // Add the user column
    $earnings_columns['user'] = __( 'User', 'gamipress' );
    return $earnings_columns;
}
add_filter( 'gamipress_earnings_columns', 'my_prefix_gamipress_earnings_new_column', 10, 2 );
function my_prefix_gamipress_earnings_render_new_column( $column_output, $column_name, $user_earning, $template_args ) {
    // Check that column is our newly added one
    if( $column_name !== 'user' ) {
        return $column_output;
    }
    $user = get_userdata( $user_earning->user_id );
    if( $user ) {
        // Add the user display name as column output
        $column_output = $user->display_name;
    }
    return $column_output;
}
add_filter( 'gamipress_earnings_render_column', 'my_prefix_gamipress_earnings_render_new_column', 10, 2 );
