# --description--

The `tr` element is used to indicate a table row. Add a `tr` element within your `thead` element. In your new `tr` element, add a `td` element, followed by three `th` elements.

The `td` element indicates a data cell, while the `th` element indicates a header cell.

# --hints--

Your `thead` element should have a `tr` element.

```js
assert(document.querySelector('thead')?.children?.[0]?.localName === 'tr');
```

Your `tr` element should have a `td` element as the first child.

```js
assert(document.querySelector('tr')?.children?.[0]?.localName === 'td');
```

Your `tr` element should have three `th` elements, after the `td` element.

```js
assert(document.querySelector('tr')?.children?.[1]?.localName === 'th');
assert(document.querySelector('tr')?.children?.[2]?.localName === 'th');
assert(document.querySelector('tr')?.children?.[3]?.localName === 'th');
```
