Table Extension

(Note: this extension is included by default within the GFM extension)

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:

composer require league/commonmark

See the installation section for more details.

Usage

Configure your Environment as usual and simply add the TableExtension provided by this package:

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 = [
    'table' => [
        'wrap' => [
            'enabled' => false,
            'tag' => 'div',
            'attributes' => [],
        ],
        'alignment_attributes' => [
            'left'   => ['align' => 'left'],
            'center' => ['align' => 'center'],
            'right'  => ['align' => 'right'],
        ],
    ],
];

// 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->convert('Some Markdown with a table in it');

Syntax

This package is fully compatible with GFM-style tables:

Simple

Code:

th | th(center) | th(right)
---|:----------:|----------:
td | td         | td

Result:

<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

| header 1 | header 2 | header 2 |
| :------- | :------: | -------: |
| cell 1.1 | cell 1.2 | cell 1.3 |
| cell 2.1 | cell 2.2 | cell 2.3 |

Configuration

Wrapping Container

You can “wrap” the table with a container element by configuring the following options:

For example, to wrap all tables within a <div class="table-responsive"> container element:

$config = [
    'table' => [
        'wrap' => [
            'enabled' => true,
            'tag' => 'div',
            'attributes' => ['class' => 'table-responsive'],
        ],
    ],
];

Alignment

You can configure the HTML attributes used for alignment via the alignment_attributes option. For example, if you wanted Bootstrap classes to be applied, you could do so like this:

$config = [
    'table' => [
        'alignment_attributes' => [
            'left' => ['class' => 'text-start'],
            'center' => ['class' => 'text-center'],
            'right' => ['class' => 'text-end'],
        ],
    ],
];

Or you could use inline styles:

$config = [
    'table' => [
        'alignment_attributes' => [
            'left' => ['style' => 'text-align:left'],
            'center' => ['style' => 'text-align:center'],
            'right' => ['style' => 'text-align:right'],
        ],
    ],
];

Or any other HTML attributes you’d like!

Credits

The Table functionality was originally built by Martin Hasoň and Webuni s.r.o. before it was merged into the core parser.
