这是一个拖放表,但我有一个问题,如何维护表中优先级列的数字序列。

/***** here i need to maintain the sequence of the numbers **********************/
<tr><td class='priority'>1</td><td>George Washington</td><td>Apple</td><td>N</td><td><a class='btn btn-delete btn-danger'>Delete</a></td></tr>

<tr><td class='priority'>5</td><td>Alexander Hamilton</td><td>Red grapes</td><td>N</td><td><a class='btn btn-delete btn-danger'>Delete</a></td></tr>

我需要列优先级像它一样移动,需要列来维护数字序列,如1,2,3,4,5等,而不是像实际的那样移动所有表代码。
