1.off移除on绑定的事件
2.列checkbox列single属性单选
3.render时changes属性可以动态改变列
4.初始化时rowStyleFormatter可以根据值改变行样式，rowClassFormatter可以根据值改变行css样式
例子：
<table class="layui-table" lay-filter="tbUsers" id="tbUsers">
<thead>
<tr>
<th lay-data="{type:'checkbox',width:50,single:true}"></th>
<th lay-data="{field:'UserName',width:100,align:'left'}">用户名</th>
<th lay-data="{field:'Address',width:150,align:'left'}">住址</th>
<th lay-data="{field:'Email',width:150,align:'left'}">邮箱</th>
<th lay-data="{field:'Mobile',width:150,hide:true,align:'left'}">联系方式</th>
<th lay-data="{field:'AddTime',width:150,align:'left',templet:formatWSDate}">创建时间</th>
</tr>
</thead>
<tbody></tbody>
</table>
<script>
rowStyleFormatter(d){
return d.Flag == "2" ? "background-color:green":"";
}
//id
table.init("tbUsers",{cellMinWidth:50,height:100,page:false,rowStyleFormatter:rowStyleFormatter});
table.reload("tbUsers",{data:[{UserId:1,UserName:"测试"}],changes:{
Email:{hide:true},
Mobile:{hide:false}
}});
table.on("row(tbUsers)",function(row){
console.log(row.data.UserName);
});
//id
var data = table.checkStatus('tbUsers').data;
if (!data.length) {
layui.layer.alert('请选择需要删除的数据！');
return;
}
//单选，获取选择行用户名
data[0].UserName
