Dcat Admin 在工具表单中使用表格表单 (table)无效，点击新增没有反应，也不报错。

这是工具表单代码

<?php

namespace App\Admin\Forms;
use Dcat\Admin\Traits\LazyWidget;
use Dcat\Admin\Contracts\LazyRenderable;
use Dcat\Admin\Form\NestedForm;
use Dcat\Admin\Widgets\Form;
class DemoForm extends Form implements LazyRenderable
{
    use LazyWidget;
    /**
     * Handle the form request.
     *
     * @param array $input
     *
     * @return mixed
     */
    public function handle(array $input)
    {
         dd($input);

        // return $this->response()->error('Your error message.');

        return $this
                ->response()
                ->success('Processed successfully.')
                ->refresh();
    }

    /**
     * Build a form here.
     */
    public function form()
    {
        $this->table('table', function (NestedForm $table) {
            $table->text('key');
            $table->text('value');
            $table->text('desc');
        });
    }

    /**
     * The data of the form.
     *
     * @return array
     */
    public function default()
    {
        return [
            'name'  => 'John Doe',
            'email' => 'John.Doe@gmail.com',
        ];
    }
}

这是具体使用的代码

<?php

        return $content
            ->body(function (Row $row){
                $tab=new Tab();
                $tab->add(3,$this->grid());
                $tab->add(1,123);
                $tab->add(2,123);
                $row->column(12,$tab->withCard());
            });
    }
    /**
     * Make a grid builder.
     *
     * @return Grid
     */
    public function grid()
    {
        return Grid::make(new Liu(), function (Grid $grid) {
            //使用工具表单
            $form=Modal::make()
                ->lg()
                ->title('321')
                ->body(DemoForm::make())
                ->button('<button class="btn btn-primary">点击打开表单</button>');
            $grid->tools($form);
            $grid->tools(DemoButton::make());
            $grid->column('id')->sortable();
            $grid->column('type');
            $grid->column('title');
            $grid->column('content');
            $grid->column('created_at');
            $grid->column('updated_at')->sortable();

            $grid->filter(function (Grid\Filter $filter) {
                $filter->equal('id');

            });
        });
    }

    public function show($id,Content $content) {
        return $content
            ->body($this->detail($id));
    }

    /**
     * Make a show builder.
     *
     * @param mixed $id
     *
     * @return Show
     */
    protected function detail($id)
    {
        return Show::make($id, new Liu(), function (Show $show) {
            $show->field('id');
            $show->field('type');
            $show->field('title');
            $show->field('content');
            $show->field('created_at');
            $show->field('updated_at');
        });
    }

    /**
     * Make a form builder.
     *
     * @return Form
     */
    protected function form()
    {
        return Form::make(new Liu(), function (Form $form) {
            $form->display('id');
            $form->text('type');
            $form->text('title');
            $form->text('content');

            $form->display('created_at');
            $form->display('updated_at');
        });
    }
}

点击新增无效
