# Table Extension
_(Note: this extension is included by default within [the GFM extension](/2.1/extensions/github-flavored-markdown/))_
The `TableExtension` adds the ability to create tables in CommonMark documents.
## Installation
This extension is bundled with `league/commonmark`. This library can be installed via Composer:
```bash
composer require league/commonmark
```
See the [installation](/2.1/installation/) section for more details.
## Usage
Configure your `Environment` as usual and simply add the `TableExtension` provided by this package:
```php
use League\CommonMark\Environment\Environment;
use League\CommonMark\Extension\CommonMark\CommonMarkCoreExtension;
use League\CommonMark\Extension\Table\TableExtension;
use League\CommonMark\MarkdownConverter;
// Define your configuration, if needed
$config = [];
// Configure the Environment with all the CommonMark parsers/renderers
$environment = new Environment($config);
$environment->addExtension(new CommonMarkCoreExtension());
// Add this extension
$environment->addExtension(new TableExtension());
// Instantiate the converter engine and start converting some Markdown!
$converter = new MarkdownConverter($environment);
echo $converter->convertToHtml('Some Markdown with a table in it');
```
## Syntax
This package is fully compatible with [GFM-style tables](https://github.github.com/gfm/#tables-extension-):
### Simple
Code:
```markdown
th | th(center) | th(right)
---|:----------:|----------:
td | td | td
```
Result:
```html
<table>
<thead>
<tr>
<th align="left">th</th>
<th align="center">th(center)</th>
<th align="right">th(right)/th>
</tr>
</thead>
<tbody>
<tr>
<td align="left">td</td>
<td align="center">td</td>
<td align="right">td</td>
</tr>
</tbody>
</table>
```
### Advanced
```markdown
| header 1 | header 2 | header 2 |
| :------- | :------: | -------: |
| cell 1.1 | cell 1.2 | cell 1.3 |
| cell 2.1 | cell 2.2 | cell 2.3 |
```
## Credits
The Table functionality was originally built by [Martin HasoĊ](https://github.com/hason) and [Webuni s.r.o.](https://www.webuni.cz) before it was merged into the core parser.
