+# Parsedown Tablespan
+
+An extension of [ParsedownExtra](https://github.com/erusev/parsedown-extra) and [Parsedown](http://parsedown.org/) that adds support for rowspan and colspan.
+
+## Installation
+
+### Composer
+
+Install the [composer package](https://packagist.org/packages/KENNYSOFT/parsedown-tablespan "The Parsedown Tablespan package on packagist.org") by running the following command:
+
+```bash
+composer require KENNYSOFT/parsedown-tablespan
+```
+
+### Manual
+
+1. Download the "Source code" from the [latest release](https://github.com/KENNYSOFT/parsedown-tablespan/releases/latest "The latest release of Parsedown Tablespan")
+2. Include `Parsedown.php`, `ParsedownExtra.php`, and `ParsedownTablespan.php`
+
+## Example
+
+```php
+$ParsedownTablespan = new ParsedownTablespan();
+
+echo $ParsedownTablespan->text('
+| >     | >           |   Colspan    | >           | for thead |
+| ----- | :---------: | -----------: | ----------- | --------- |
+| Lorem | ipsum       |    dolor     | sit         | amet      |
+| ^     | -           |      >       | right align | .         |
+| ,     | >           | center align | >           | 2x2 cell  |
+| >     | another 2x2 |      +       | >           | ^         |
+| >     | ^           |              |             | !         |
+');
+```
+
+Prints:
+
+<table>
+<thead>
+<tr>
+<th align="center" colspan="3">Colspan</th>
+<th colspan="2">for thead</th>
+</tr>
+</thead>
+<tbody>
+<tr>
+<td rowspan="2">Lorem</td>
+<td align="center">ipsum</td>
+<td align="right">dolor</td>
+<td>sit</td>
+<td>amet</td>
+</tr>
+<tr>
+<td align="center">-</td>
+<td align="right" colspan="2">right align</td>
+<td>.</td>
+</tr>
+<tr>
+<td>,</td>
+<td align="center" colspan="2">center align</td>
+<td colspan="2" rowspan="2">2x2 cell</td>
+</tr>
+<tr>
+<td align="center" colspan="2" rowspan="2">another 2x2</td>
+<td align="right">+</td>
+</tr>
+<tr>
+<td align="right"></td>
+<td></td>
+<td>!</td>
+</tr>
+</tbody>
+</table>
+
+_(Since GFM does not accept style attribute for cells, upper table is made with `align` attribute which is not supported in HTML5, just to show what will be generated.)_
