Yii2 GridView中的HTML(HTML in Yii2 GridView)

 我试图在位于Yii2 GridView中的列中显示一些HTML编码的字符串作为纯HTML。 来自数据库的字符串如下所示：  
Testing &lt;span class=&#039;test&#039;&gt;HTML&lt;/span&gt;
 
 如果我只是使用HTML解码Html::decode($theStringAbove);显示它Html::decode($theStringAbove); 然后我在专栏中得到这个：  
Testing <span class='test'>HTML</span>
 
 但是，我的目标只是获取Testing HTML并在代码中围绕HTML单词使用span标记，但不显示为字符串。  
 我已经尝试为format属性设置不同的值，例如raw ， url和html ，但没有成功。 我也没有问题编写自定义函数来返回value属性旁边的正确输出，这只是我无法弄清楚如何获得我需要的输出。 欢迎任何建议，谢谢！  
 编辑：这是一个小代码片段，如果这有用：  
[ 'format' => 'raw',
  'value' => function($model) { return Html::decode($model->text); },
  'label' => Yii::t('app', 'Some Label')]

I'm trying to display some HTML encoded strings as pure HTML in a column positioned in Yii2 GridView. The string that comes from the database looks like this: 
Testing &lt;span class=&#039;test&#039;&gt;HTML&lt;/span&gt;
 
If I just display it using HTML decode Html::decode($theStringAbove); then I get this in the column: 
Testing <span class='test'>HTML</span>
 
However, what I'm aiming at is simply getting Testing HTML and having the span tag around the HTML word in the code but not displayed as a string. 
I've tried setting different values to the format attribute such as raw, url and html to no success. I also have no problem writing a custom function to return the correct output next to the value attribute, it's just that I can't figure out how to get to the output I need. Any suggestions are welcome, thank you! 
EDIT: Here's a small code snippet if that's helpful: 
[ 'format' => 'raw',
  'value' => function($model) { return Html::decode($model->text); },
  'label' => Yii::t('app', 'Some Label')]

 你必须推迟build_ast的定义，直到ast是一个完整的类型：  
inline ast build_ast(); //here we want to use object of ast type
 
 _{inline在这里使这个声明在功能上与你在例子中所做的一致。} _{您可能希望将其删除并将build_ast移动到实现文件}  
 在结构定义之外：  
ast parser::build_ast()
{
    node *ret = new node;
    return ast(ret);
}
 
 要转发声明node ，您需要在parser定义中执行此操作。 换句话说，你不能在没有定义外层的情况下转发声明一个内部类。  
struct parser
{
    struct node;
    // ...
};
 
 然后您可以继续定义：  
struct parser::node
{
    node *parent;
};

You have to defer the definition of build_ast until ast is a complete type: 
inline ast build_ast(); //here we want to use object of ast type
 
_{inline is here to make this declaration functionally identical to what you had in example. You may want to remove it and move build_ast to an implementation file}  
Outside of the struct definition: 
ast parser::build_ast()
{
    node *ret = new node;
    return ast(ret);
}
 
To forward-declare node, you need to do this within parser definition. In other words, you cannot forward-declare an inner class without defining the outer. 
struct parser
{
    struct node;
    // ...
};
 
You can then proceed with a definition: 
struct parser::node
{
    node *parent;
};
