How to do tables in GitHub flavoured Markdown

tables.md

This:

heading 1 | heading 2 | heading 3
--- | --- | ---
abc | bcd | cde
def | efg | fgh

becomes this:

heading 1	heading 2	heading 3
abc	bcd	cde
def	efg	fgh

---

You can also use plain old HTML tables. This:

<table>
  <tr>
    <th>heading 1</th>
    <th>heading 2</th>
    <th>heading 3</th>
  </tr>
  <tr>
    <td>abc</td>
    <td>bcd</td>
    <td>cde</td>
  </tr>
  <tr>
    <td>def</td>
    <td>efg</td>
    <td>fgh</td>
  </tr>
</table>

becomes this:

heading 1	heading 2	heading 3
Part Count Overage Using HTML is handy because you can do more advanced things like nested tables, or adding lists within cells.
