添加表格

上面表格的markdown写法如下：

注意：上面的|必须为英文输入法下面的字符，中文输入法下是不同的字符，而且不易看出差别。

insert an image

To insert the image, just use the path under the base url, for me, it is /GitBlogs/images/.png, for example

1

![image annotation](/images/001_ios_frameworks.png)

To define the size of the image:

1

![image annotation](/images/001_ios_frameworks.png =200x300)

Or you can omit the height of the image:

1

![image annotation](/images/001_ios_frameworks.png =200x)

If the aspect ratio you define is not consistent with the original image, the height will be omitted automatically. That is to say, just define the width you want, and the system will calculate the height for you.
