我想为公司创建类别，但出现以下错误：sqlstate[hy000]：常规错误：1005无法创建表 sanat . #sql-53e_e7d （errno:150“外键约束格式不正确”）（sql:alter table company_category 添加约束 company_category_company_id_foreign 外键( company_id )参考文献 companies ( id )删除时（级联）
这是我的类别迁移代码：

public function up()
{
    Schema::create('categories', function (Blueprint $table) {
        $table->increments('id')->unsigned();
        $table->string('name');
        $table->string('slug');
        $table->string('description')->nullable();
        $table->string('type');
        $table->string('imageUrl')->nullable();
        $table->timestamps();
    });
    Schema::create('article_category', function (Blueprint $table) {
        $table->integer('article_id')->unsigned();
        $table->foreign('article_id')->references('id')->on('articles')->onDelete('cascade');
        $table->integer('category_id')->unsigned();
        $table->foreign('category_id')->references('id')->on('categories')->onDelete('cascade');
        $table->primary(['article_id', 'category_id']);
    });
    Schema::create('company_category', function (Blueprint $table) {
        $table->integer('company_id')->unsigned();
        $table->foreign('company_id')->references('id')->on('companies')->onDelete('cascade');
        $table->integer('category_id')->unsigned();
        $table->foreign('category_id')->references('id')->on('categories')->onDelete('cascade');
        $table->primary(['company_id', 'category_id']);
    });

}

所以company表和categories表不创建。当我删除此项时：

Schema::create('company_category', function (Blueprint $table) {
    $table->integer('company_id')->unsigned();
    $table->foreign('company_id')->references('id')->on('companies')->onDelete('cascade');
    $table->integer('category_id')->unsigned();
    $table->foreign('category_id')->references('id')->on('categories')->onDelete('cascade');
    $table->primary(['company_id', 'category_id']);
});

php artisan迁移成功。问题出在哪里
这是我的公司迁移：

Schema::create('companies', function (Blueprint $table) {
    $table->increments('id')->unsigned();
    $table->integer('user_id')->unsigned();
    $table->foreign('user_id')->references('id')->on('users')->onDelete('cascade');
    $table->boolean('active')->default(false);
    $table->string('name');
    $table->string('email')->unique();
    $table->string('slug');
    $table->text('aboutUs');
    $table->integer('tell');
    $table->string('address');
    $table->string('tag');
    $table->string('logoUrl');
    $table->string('slideUrl')->unique();
    $table->string('facebookUrl');
    $table->string('instagramUrl');
    $table->string('telegramUrl');
    $table->string('whatsAppUrl');
    $table->string('websiteUrl');
    $table->timestamps();
});
