This example shows implementing a basic Modal component with a heading, body content, and action buttons using Scale web components. It depends on scale-modal and scale-button elements from the Scale Design System. Inputs include props like heading and opened state; outputs are events like scale-open and scale-close. Limitations: Requires proper component registration and may need additional CSS for theming; deprecated events should be avoided.

```html
<scale-modal heading="Today is your lucky day" id="modal">
  <p>Hello. Welcome. What a pleasure it is to have you.</p>
  <scale-button slot="action" variant="secondary" onclick="closeModal()">
    Cancel
  </scale-button>
  <scale-button slot="action"> Primary Action </scale-button>
</scale-modal>
```

```javascript
const modal = document.getElementById('modal');
function openModal() {
  modal.opened = true;
}
function closeModal() {
  modal.opened = false;
}
```

  }

  .theme-example scale-button[variant=\"plain\"]::part(base) {
    background: transparent;
    border: 2px solid currentColor;
  }
</style>

<body class=\"theme-example\"></body>

const App = () => (
  <div>
    <scale-button>Click</scale-button>
  </div>
);

export default App;

### Define Table Fields Configuration in JavaScript

Source: https://telekom.github.io/scale/index_path=%2Fdocs%2Fcomponents-data-grid--select-cell

Creates a `fields` array that defines each column's type, label, and other options for the Scale table. This JavaScript configuration is required to match the structure of the `rows` data. Adjust the objects to include additional field options as needed.

```JavaScript
const fields = [ { type: 'number', label: 'ID', }, { type: 'text', label:
'Name', }, { type: 'date', label: 'Time', }, ];
```
