Extension for [`mdast-util-from-markdown`][from-markdown] and/or
[`mdast-util-to-markdown`][to-markdown] to support GitHub flavored markdown
tables in **[mdast][]**.
When parsing (`from-markdown`), must be combined with
[`micromark-extension-gfm-table`][extension].

You probably shouldn’t use this package directly, but instead use
[`remark-gfm`][remark-gfm] with **[remark][]**.

## Install

[npm][]:

```sh
npm install mdast-util-gfm-table
```

## Use

Say we have the following file, `example.md`:

```markdown
| a | b | c | d |
| - | :- | -: | :-: |
| e | f |
| g | h | i | j | k |
```

And our script, `example.js`, looks as follows:

```js
var fs = require('fs')
var fromMarkdown = require('mdast-util-from-markdown')
var toMarkdown = require('mdast-util-to-markdown')
var syntax = require('micromark-extension-gfm-table')
var table = require('mdast-util-gfm-table')

var doc = fs.readFileSync('example.md')

var tree = fromMarkdown(doc, {
  extensions: [syntax],
  mdastExtensions: [table.fromMarkdown]
})

console.log(tree)

var out = toMarkdown(tree, {extensions: [table.toMarkdown()]})

console.log(out)
```

Now, running `node example` yields (positional info removed for the sake of
brevity):

```js
{
  type: 'root',
  children: [
    {
      type: 'table',
      align: [null, 'left', 'right', 'center'],
      children: [
        {
          type: 'tableRow',
          children: [
            {type: 'tableCell', children: [{type: 'text', value: 'a'}]},
            {type: 'tableCell', children: [{type: 'text', value: 'b'}]},
            {type: 'tableCell', children: [{type: 'text', value: 'c'}]},
            {type: 'tableCell', children: [{type: 'text', value: 'd'}]}
          ]
        },
        {
          type: 'tableRow',
          children: [
            {type: 'tableCell', children: [{type: 'text', value: 'e'}]},
            {type: 'tableCell', children: [{type: 'text', value: 'f'}]}
          ]
        },
        {
          type: 'tableRow',
          children: [
            {type: 'tableCell', children: [{type: 'text', value: 'g'}]},
            {type: 'tableCell', children: [{type: 'text', value: 'h'}]},
            {type: 'tableCell', children: [{type: 'text', value: 'i'}]},
            {type: 'tableCell', children: [{type: 'text', value: 'j'}]},
            {type: 'tableCell', children: [{type: 'text', value: 'k'}]}
          ]
        }
      ]
    }
  ]
}
```

```markdown
| a | b  |  c |  d  |   |
| - | :- | -: | :-: | - |
| e | f  |    |     |   |
| g | h  |  i |  j  | k |
```
