当使用多列布局时，使用div+css布局感觉代码不好控制，使用table结构清晰，布局简洁，不用写一堆的css来定位，控制大小的。
例子：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport"
content="width=device-width, initial-scale=1, maximum-scale=1">
<title>incomingDispatches 管理</title> #include("/static/my/header.html")
<style type="text/css">
.frm-layout{
100%;
border-collapse: separate;
border-spacing: 10px;
}
.frm-layout td.title{
text-align: right;
padding-right: 10px;
85px;
}
/* 防止下拉框的下拉列表被隐藏---必须设置--- */
.frm-layout .layui-table-cell { overflow: visible !important; }
/* 使得下拉框与单元格刚好合适 */
.frm-layout td .layui-form-select{
margin-top: 0px;
margin-left: 0px;
margin-right: 0px;
}
</style>
</head>
<body>
<form id="frmEdit" class="layui-form" lay-filter="frm">
<input type="hidden" name="id" lay-verify="" placeholder=""
autocomplete="off" class="layui-input" value="">
