Learning jquery (1), the first grid that can be dragged

When I was interviewing some days ago, I was asked if I would use jquery? I said no. Could I use. Net gridview? I wrote CSS directly when I said it was rarely used, so I was rejected... haha, joke. Of course there are other reasons.
I don't have to do anything recently. I want to learn jquery, and then I want to write a grid that can drag and drop columns (in fact, there are powerful components like flexigrid. Why do I write this ), this will speed up your development.
When I got started with jquery, I found it very powerful. $ and each alone made me very useful. I used to write dom for a long time. I just took a look at it. Slowly, I have a certain understanding of the Javascript writing method, and I will use it as soon as I learn it. Finally, I made this stuff.
No ff and IE6, so I only used IE7 for testing. If you have any suggestions or suggestions, please give me some suggestions.

In fact, the basic principle is to first create a div box, and then write data in JSON format to it. The table header and format are defined in the data.
Simple functions.
I am very happy to see the reply. As required, I continued to write a function that reads data from the table and named it version 1.0.2. Haha

However, it takes a short time and is not robust, that is, some fields must be entered in the table. If not, an error may occur. Continue to modify it.
