解决了。

废话不多说，demo代码如下：

public function up()
{
    Schema::create('ArticleExtend', function (Blueprint $table) {
        $table->increments('id');
        $table->string('extend_key');
        $table->text('extend_value');
        $table->timestamp('published_at');
        $table->timestamps();
        $table->tinyInteger('flag');
    });
}

找了找文档，类似tinyInteger的函数中，没有用于设置默认值的参数，也没有看到Scheam里有default字眼的函数。请问如何给字段设置默认值呢？@JellyBool
