我正在尝试创建一个外键，artisan 没有显示任何错误，只是没有创建我的外键，这可能是我的代码：

1°表：

Schema::create('cooperados', function (Blueprint $table) {
        $table->bigIncrements('id');
        $table->timestamps();
        $table->string('nameCoop', 255);
        $table->integer('numCoop');
        $table->string('cpfCoop', 11);
        $table->date('dtCad');
        $table->date('dtDem')->nullable();
        $table->text('description')->nullable();
        $table->decimal('subscritas', 6, 2);
        $table->decimal('integralizadas', 6,2)->nullable();
        $table->decimal('aintegralizar', 6,2)->nullable();
        $table->enum('status', ['ativo','inativo'])->default('ativo');
    });

外键表

public function up()
    {
        Schema::create('mov', function (Blueprint $table) {
            $table->bigIncrements('idMov');
            $table->timestamps();
            $table->integer('id_coop')->unsigned;
            $table->foreign('id_coop')->references('id')->on('cooperados');
            $table->decimal('valor', 6, 2);
        });
    }
