这篇文章将为大家详细讲解有关java如何实现表格tr拖动，小编觉得挺实用的，因此分享给大家做个参考，希望大家阅读完这篇文章后可以有所收获。
1. 简单，只需理解基本的概念，就可以编写适合于各种情况的应用程序；2. 面向对象；3. 分布性，Java是面向网络的语言；4. 鲁棒性，java提供自动垃圾收集来进行内存管理，防止程序员在管理内存时容易产生的错误。；5. 安全性，用于网络、分布环境下的Java必须防止病毒的入侵。6. 体系结构中立，只要安装了Java运行时系统，就可在任意处理器上运行。7. 可移植性，Java可以方便地移植到网络上的不同机器。8.解释执行，Java解释器直接对Java字节码进行解释执行。
实现功能：实现表格tr拖动，并保存因为拖动改变的等级.
