将Table表格导出到Excel

1.导出当前页

效果如下:

前台代码:

@{
    Layout = null;
}

<!DOCTYPE html>

<html>
<head>
    <meta name="viewport" content="width=device-width" />
    <title>Index</title>
    <style>
        DIV.viciao {
            MARGIN-TOP: 20px;
            MARGIN-BOTTOM: 10px;
        }

            DIV.viciao A {

PS：上面是导出【当前页】的内容，如果想导出【所有的】。原理一样，添加个隐藏域就行了，然后将所有查询到的值加载到这个隐藏域里面。之后就可以按照上面的方法继续啦~
