Method Dcat\Page\Admin\Controllers\AdminController::formatConfigData does not exist.

[OliverGarfield]

在Admin/Controllers/AdminController.php中 $grid->config('配置')->display('详细')->expand(function () use ($self) {

        if (!$this->config) {

            return;

        }



        return $self->formatConfigData((array) $this->config);

});

return $self->formatConfigData((array) $this->config); formatConfigData无法访问 因为是protected
