操作方法<BR>一
键盘操作<BR>1.Insert键增加一行，并复制最后一行内容，Delete键删除最后一行，该操作用以调节表格总大小；<BR>2.Tab键横向移动光标，Enter键纵向移动光标，符合Excle用户习惯；<BR>二
页面操作<BR>1.全选：选择全部行，再次执行释放全部行；<BR>2.复制所选：复制已经选择的行及其内容；<BR>3.删除所选：删除已经选择的行；<BR>4.清空所选：清除所有单元格(input)中的内容；<BR>5.提交：发送数据内容到服务器<BR>三
智能操作<BR>双击单元格将弹出菜单，菜单自动收集该列上所有不重复的已输入内容，为重复输入数据提供了方便。<BR></BODY></HTML>
