Question: I would like to make a mass modification to attribute sets. I would like to add a series of attributes among those not yet assigned to the attributes set (200) in the "General" section. 

I would like to make this change from the database.
Can anyone help me on how to proceed? What tables contain this data?

I must repeat the operation in the photo for 200 set of attributes, assigning each part a portion of unassigned attributes

Answer: 
Discovered I was missing the Config setting:

```
/**
 * @var \Magento\Cms\Model\Wysiwyg\Config
 */
protected $_wysiwygConfig;

/**
 * @param \Magento\Backend\Block\Template\Context $context
 * @param \Magento\Framework\Registry $registry
 * @param \Magento\Framework\Data\FormFactory $formFactory
 * @param \Magento\Cms\Model\Wysiwyg\Config $wysiwygConfig
 * @param \Magento\Store\Model\System\Store $systemStore
 * @param array $data
 */
public function __construct(
    \Magento\Backend\Block\Template\Context $context,
    \Magento\Cms\Model\Wysiwyg\Config $wysiwygConfig,
    array $data = []
) {
    $this->_wysiwygConfig = $wysiwygConfig;
    parent::__construct($context, $data);
}

```

**Meaning I could do the following:**

```
$fieldset->addField(
    'content',
    'editor',
    [
        'name' => 'content',
        'label' => __('Body'),
        'title' => __('Body'),
        'rows' => '5',
        'cols' => '30',
        'wysiwyg' => true,
        'config' => $this->_wysiwygConfig->getConfig(),
        'required' => true
    ]
);

```

Type must be set to *editor* and wysiwyg set to *true* for this to work.
It is very simple dont do all this things just put below code in 
app\code\NameSpace\Module\view\adminhtml\layout\module\_module\_form.xml

```
<field name="content">
            <argument name="data" xsi:type="array">
                <item name="config" xsi:type="array">
                    <item name="label" xsi:type="string"/>
                    <item name="formElement" xsi:type="string">wysiwyg</item>
                    <item name="source" xsi:type="string">block</item>
                    <item name="wysiwyg" xsi:type="boolean">true</item>
                    <item name="dataScope" xsi:type="string">content</item>
                    <item name="additionalClasses" xsi:type="string">admin__field-wide</item>
                    <item name="validation" xsi:type="array">
                        <item name="required-entry" xsi:type="boolean">true</item>
                    </item>
                </item>
            </argument>
        </field>

```
