控制表格的多选和反选,直接上代码,顺便安利一个小知识点:tr的底边框不显示的问题,解决办法是:table{border-collapse:collapse;}
<!DOCTYPE html>
<html>
<head>
<title></title>
<style>
*{margin:0;padding:0;}
table{border-collapse:collapse}
.detail_tb {width: 100%;border: 1px solid #ccc;}
.detail_tb .fied_header {height: 38px;line-height: 38px;border-left: none;border-bottom: 1px solid #ccc;background-color: #ececec;}
.detail_tb .fied_header th {text-align: center;border-right: 1px solid #ccc;color: #333;font-size: 14px;}
.detail_tb .fied_header th input {vertical-align: middle;}
.detail_tb tr {height: 38px;line-height: 38px;border-left: none;border-bottom: 1px solid #ccc;background-color: #fff;}
.detail_tb tr td {text-align: center;border-right: 1px solid #ccc;color: #666;font-size: 14px;}
.detail_tb tr td input {float: left;margin: 12px 5px 0 10px;}
