Php 过滤和排序在数字和日期方面无法按预期工作

我在最新的Laravel 8上使用Laravel兰花。 我的供应商模型和迁移

 Schema::create('vendors', function (Blueprint $table) {
            $table->id();
            $table->string('display_name');
            $table->string('contact_name');
            $table->string('email')->unique();
            $table->string('url')->unique();
            $table->string('password');
            $table->string('contact');
            $table->text('bio')->nullable();
            $table->boolean('sponsored')->default(false);
            $table->boolean('is_freelance')->default(false);
            $table->boolean('is_commisioned')->default(false);
            $table->boolean('auto_approve')->default(false);
            $table->boolean('status')->default(true);
            $table->timestamps();
        });

protected $fillable = [
        'display_name',
        'contact_name',
        'url',
        'email',
        'password',
        'contact',
        'bio',
        'status',
        'sponsored',
        'is_freelance',
        'is_commisioned',
        'auto_approve'

    ];

    protected $allowedFilters = [
        'display_name',
        'contact_name',
        'url',
        'email',
        'contact',
        'status',
        'sponsored',
        'is_freelance',
        'is_commisioned',
        'auto_approve',
        'created_at',
        'updated_at',
    ];

    protected $allowedSorts = [
        'display_name',
        'contact_name',
        'url',
        'email',
        'status',
        'sponsored',
        'is_freelance',
        'is_commisioned',
        'auto_approve',
        'created_at',
        'updated_at',
    ];

TD::make('email', 'Email')
                ->render(function (Vendor $vendor) {
                    return Link::make($vendor->email)
                        ->route('platform.vendor.edit', $vendor);
                })->filter(TD::FILTER_TEXT),

            TD::make('url', 'Url')
                ->render(function (Vendor $vendor) {
                    return Link::make($vendor->url)
                        ->route('platform.vendor.edit', $vendor);
                })->filter(TD::FILTER_TEXT),
            TD::make('display_name', 'Disp Name')->filter(TD::FILTER_TEXT),
            TD::make('contact_name', 'Contact Name')->filter(TD::FILTER_TEXT)->sort(),
            TD::make('contact', 'Contact')->filter(TD::FILTER_TEXT),
            TD::make('status', 'Status')->filter(TD::FILTER_TEXT),
            TD::make('created_at', 'Created')->filter(TD::FILTER_DATE)->sort(),
            TD::make('updated_at', 'Last edit')->filter(TD::FILTER_DATE)->sort()
                ->render(function ($vendor) {
                    if ($vendor->updated_at) {
                        $date = $vendor->updated_at->toDayDateTimeString();
                    } else {
                        $date = 'n/a';
                    }
                    return $date;
                }),

我的兰花布局为供应商

 Schema::create('vendors', function (Blueprint $table) {
            $table->id();
            $table->string('display_name');
            $table->string('contact_name');
            $table->string('email')->unique();
            $table->string('url')->unique();
            $table->string('password');
            $table->string('contact');
            $table->text('bio')->nullable();
            $table->boolean('sponsored')->default(false);
            $table->boolean('is_freelance')->default(false);
            $table->boolean('is_commisioned')->default(false);
            $table->boolean('auto_approve')->default(false);
            $table->boolean('status')->default(true);
            $table->timestamps();
        });

protected $fillable = [
        'display_name',
        'contact_name',
        'url',
        'email',
        'password',
        'contact',
        'bio',
        'status',
        'sponsored',
        'is_freelance',
        'is_commisioned',
        'auto_approve'

    ];

    protected $allowedFilters = [
        'display_name',
        'contact_name',
        'url',
        'email',
        'contact',
        'status',
        'sponsored',
        'is_freelance',
        'is_commisioned',
        'auto_approve',
        'created_at',
        'updated_at',
    ];

    protected $allowedSorts = [

        'is_commisioned',
        'auto_approve',
        'created_at',
        'updated_at',
    ];

TD::make('email', 'Email')
                ->render(function (Vendor $vendor) {
                    return Link::make($vendor->email)
                        ->route('platform.vendor.edit', $vendor);
                })->filter(TD::FILTER_TEXT),

            TD::make('url', 'Url')
                ->render(function (Vendor $vendor) {
                    return Link::make($vendor->url)
                        ->route('platform.vendor.edit', $vendor);
                })->filter(TD::FILTER_TEXT),
            TD::make('display_name', 'Disp Name')->filter(TD::FILTER_TEXT),
            TD::make('contact_name', 'Contact Name')->filter(TD::FILTER_TEXT)->sort(),
            TD::make('contact', 'Contact')->filter(TD::FILTER_TEXT),
            TD::make('status', 'Status')->filter(TD::FILTER_TEXT),
            TD::make('created_at', 'Created')->filter(TD::FILTER_DATE)->sort(),
            TD::make('updated_at', 'Last edit')->filter(TD::FILTER_DATE)->sort()
                ->render(function ($vendor) {
                    if ($vendor->updated_at) {
                        $date = $vendor->updated_at->toDayDateTimeString();
                    } else {
                        $date = 'n/a';
                    }
                    return $date;
                }),

问题1：对于联系人筛选器，我必须按完整的联系人号码进行搜索，它不像文本筛选器那样可以按任意数量的字符进行搜索。对于包含数字数据的其他字符串列也是如此

问题2：日期过滤器不工作。

谢谢你的帮助。非常感谢
