<title>可以全选反选删除的表格</title>

body,table

//定义嵌套数组

var datas = [["张三", 30, "南昌"], ["李四", 25, "北京"], ["王五", 20, "郑州"],

["赵六", 19, "武汉"], ["李莫", 18, "深圳"], ["罗成", 33, "重庆"],

["王平", 31, "天津"], ["刘萍", 22, "上海"], ["杨丽", 17, "石家庄"],

["郭丽", 30, "广州"]];

//动态创建表格

//设置网格间隔色和高亮显示

var oldClassName; //记住行的背景色

//复选框全选函数

function checkAll() {
