寻找Markdown配置文件

一般在用户的数据目录，例如:

C:\Users\xxx\AppData\Local\MarkdownPad2\MarkdownPad2.exe_Url_xxx\2.4.4.40074\user.config

启用Markdown扩展模式

添加或者修改一些数据

<setting name="Markdown_Extra_ExtraMode" serializeAs="String">
    <value>True</value>
</setting>
<setting name="Markdown_MarkdownProcessor" serializeAs="String">
    <value>MarkdownExtraMode</value>
</setting>

验证Markdown扩展模式

添加表格进行验证

Tables Are Cool
col 3 is right-aligned $1600
col 2 is centered $12
zebra stripes are neat $1

表格代码：

| Tables        | Are           | Cool  |
| ------------- |:-------------:| -----:|
| col 3 is      | right-aligned | $1600 |
| col 2 is      | centered      |   $12 |
| zebra stripes | are neat      |    $1 |
