【问题描述】：
我是 Angular 2 的新手，正在尝试配置 ag-grid。控制台上有一些关于 ag-grid 的错误。我已经解决了。现在控制台上除了一个错误之外没有错误，但它与 ag-grid 无关。但仍然没有显示网格。 这是代码： 在 Package.json 添加：
"ag-grid": "^7.1.0",
"ag-grid-ng2": "^7.1.2",
"ag-grid-enterprise": "^7.1.0"
在布局中添加 CSS（使用 Angular 2 和 .net core(MVC)）：
<link href="~/lib/ag-grid/dist/styles/ag-grid.css" rel="stylesheet" />
<link href="~/lib/ag-grid/dist/styles/theme-fresh.css" rel="stylesheet" />
在@ngModule 中添加
AgGridModule.withComponents([AboutComponent.AboutComponent ]),
关于是我使用 ag-grid 的组件
Here is the about component:
import { Component, OnInit } from "@angular/core";
import { Routes, RouterModule } from "@angular/router";
import PageService = require("../../services/page.service");
import { AgGridModule } from "ag-grid-ng2/main";
import { GridOptions } from "ag-grid/main";
@Component({
//no need for selector as it will be loaded via routing
templateUrl: "/page/index"
})
export class PageComponent implements OnInit {
private pages;
private gridOptions: GridOptions;
public showGrid: boolean;
public rowData: any[];
private columnDefs: any[];
public rowCount: string;
constructor(private pageService: PageService.PageService) {
// we pass an empty gridOptions in, so we can grab the api out
this.gridOptions = <GridOptions>{};
this.createRowData();
this.createColumnDefs();
this.showGrid = true;
}
ngOnInit(): void {
//this.pages = this.pageService.getAll().subscribe(pages => this.pages = pages.Content);
}
private createRowData() {
const rowData: any[] = [];
for (let i = 0; i < 10000; i++) {
const countryData = [];
rowData.push({
name: "Zeshan Munir",
skills: {
android: Math.random() < 0.4,
html5: Math.random() < 0.4,
mac: Math.random() < 0.4,
windows: Math.random() < 0.4,
css: Math.random() < 0.4
},
address: "Lahore",
years: Math.round(Math.random() * 100),
proficiency: Math.round(Math.random() * 100),
country: "Pakistan",
continent: "Asia",
language: "en-pk",
mobile: createRandomPhoneNumber(),
landline: createRandomPhoneNumber()
});
}
this.rowData = rowData;
}
private createColumnDefs() {
this.columnDefs = [
{
headerName: "#",
width: 30,
checkboxSelection: true,
suppressSorting: true,
suppressMenu: true,
pinned: true
},
{
headerName: "Employee",
children: [
{
headerName: "Name",
field: "name",
width: 150,
pinned: true
},
{
headerName: "Country",
field: "country",
width: 150,
cellRenderer: countryCellRenderer,
pinned: true,
filterParams: { cellRenderer: countryCellRenderer, cellHeight: 20 }
},
]
},
{
headerName: "IT Skills",
children: [
{
headerName: "Skills",
width: 125,
suppressSorting: true,
cellRenderer: skillsCellRenderer,
filter: ""
},
{
headerName: "Proficiency",
field: "proficiency",
width: 120,
cellRenderer: percentCellRenderer,
filter: ""
},
]
},
{
headerName: "Contact",
children: [
{ headerName: "Mobile", field: "mobile", width: 150, filter: "text" },
{ headerName: "Land-line", field: "landline", width: 150, filter: "text" },
{ headerName: "Address", field: "address", width: 500, filter: "text" }
]
}
];
}
这里是html：
<ag-grid-ng2 #agGrid enable-sorting="true" enable-filter="true" row-height="22" row-selection="multiple" [columnDefs]="columnDefs" [showToolPanel]="showToolPanel" [rowData]="rowData"
(cell-clicked)="onCellClicked($event)" (column-resized)="onColumnEvent($event)" class="ag-fresh"
>
</ag-grid-ng2>
我检查了页面，这是屏幕截图
这是控制台错误，但这与 ag-grid 无关
现在我不知道为什么网格没有显示。提前致谢。

This discussion 可能会帮助您指出正确的方向...似乎 Angular 可能会因为处于开发模式而陷入困境，其中 10000 行试图渲染到 ng-reflect 的 DOM 中-行数据。请务必了解 davidagee 在该线程中所说的内容

感谢您的回复。我不知道 ng-reflect，但问题不在于 ng-reflect。实际上，网格是在 DOM 上渲染的，但默认情况下它的宽度是 0px。我只是设置它。它显示得很完美。
