我正在教自己如何使用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此内容部分 .
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，我已成功在本地运行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">
<meta name="generator" content="Project Emerald" />
<title>Data Grid</title>

解决了 . 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，我忘记了最重要的
html标签定义 . 这是修复 .Before:
After:
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 .
