我在教自己如何使用Polymer [1.0]，我正在尝试实现数据网格。问题是......聚合物没有数据网格作为基础铁/纸/核心元素，所以我不得不出去找一个。
幸运的是，有一个很好的遵循Google Material Design设计规范，所以my intention is to use this one！
我的页面已设置为左页抽屉，顶部页眉和内容部分。我希望数据网格进入这个内容部分。
我面临的问题是DOM似乎没有呈现数据网格组件表。就好像它没有运行那些脚本并填充Angular数据。我的观点是它与Polymer元素的自包含方式有关，因此数据网格脚本没有达到它。
通过将HTML放入test.html文件，并将JS添加到测试HTML页面底部的<script>标记，我已在本地成功运行this Codepen。一切都很好。当我尝试复制并粘贴到我的应用程序中时，会发生一些事情并且网格不会呈现。
我的index.html代码如下：
<!doctype html>
<html lang="">
<head>
<meta charset="utf-8">
<meta name="description" content="">
<meta name="viewport" content="width=device-width, initial-scale=1">

解决。解决方案很简单，对于那些知道他们在Angular方面做了什么的人来说，这一点很明显。
我应该提到我也是Angular的新手，我忘记了所有重要的html标签定义。这是修复。
<强>之前：
<html lang="">
<强>后：
<html lang="en" ng-app="demoApp" class="ng-scope">
数据网格和默认的Polymer元素样式之间存在一些样式冲突，但这些样式更容易理清。
