在 Angular 中使用 SpreadJS

可以通过以下方式在 Angular 项目中使用 SpreadJS:

type=warning

注意: SpreadJS 支持 Angular 版本 11、12、13、14 、15、16 和 17

Angular 版本 13 已经移除了对 IE11 的支持

使用节点包管理器

此方法包括以下步骤:

  1. 全局安装 Angular CLI

    打开命令提示符窗口,然后键入以下命令:

    npm install -g @angular/cli 
  2. 使用 Angular CLI 创建一个新项目

    接下来,您需要使用以下命令创建一个新项目:

    ng new spread-sheets-angular-cli
    cd spread-sheets-angular-cli
  3. 安装 SpreadJS NPM 包

    现在,您可以使用以下命令安装 SpreadJS NPM 软件包:

    npm install @grapecity-software/spread-sheets
    npm install @grapecity-software/spread-sheets-angular
  4. 在 angular.json 中配置 SpreadJS CSS

    现在,您可以在 angular.json 中配置 SpreadJS CSS,如下所示:

    {
      ...
      "projects":{
        "spread-sheets-angular-cli":{
          ...
          "architect":{
            ...
            "build":{
              ...
              options:{
                ...
                "styles": [
                  "node_modules/@grapecity-software/spread-sheets/styles/gc.spread.sheets.excel2016darkGray.css"
                ],
                ...
              }
              ...
            }
            ...
          }
          ...
        }}
      ...
    }
  5. 在 Angular 应用程序中使用 SpreadJS。

    现在,您可以修改 app.module.ts 以导入 SpreadJS 模块,如下所示:

    import { BrowserModule } from '@angular/platform-browser';
    import { NgModule } from '@angular/core';
    import { AppComponent } from './app.component';
    import { SpreadSheetsModule } from "@grapecity-software/spread-sheets-angular";
    @NgModule({
    declarations: [AppComponent],
    imports: [BrowserModule,SpreadSheetsModule],
    providers: [],
    bootstrap: [AppComponent]
    })
    export class AppModule { }

    修改 app.component.html 以查看 SpreadJS 组件,如下所示:

    <gc-spread-sheets [backColor]="spreadBackColor" [hostStyle]="hostStyle" (workbookInitialized)="workbookInit($event)"><gc-worksheet [name]="sheetName" [dataSource]="data">
           <gc-column dataField="Name" width=300></gc-column>
           <gc-column dataField="Category" [width]=columnWidth></gc-column>
           <gc-column dataField="Price" [width]=columnWidth formatter="$ #.00"></gc-column>
           <gc-column dataField="Shopping Place" [width]=columnWidth></gc-column></gc-worksheet>
    </gc-spread-sheets>

    修改 app.component.ts 为 SpreadJS 组件准备数据,如下所示:

    import { Component } from '@angular/core';
    import * as GC from "@grapecity-software/spread-sheets";
    @Component({
      selector: 'app-root',
      templateUrl: './app.component.html',
      styleUrls: ['./app.component.css']
    })
    export class AppComponent {
      spreadBackColor = 'aliceblue';
      sheetName = 'Goods List';
      hostStyle = {
        width: '800px',
        height: '600px'
      };
      data = [
        { Name: 'Apple', Category: 'Fruit', Price: 1, 'Shopping Place': 'Wal-Mart' },
        { Name: 'Potato', Category: 'Fruit', Price: 2.01, 'Shopping Place': 'Other' },
        { Name: 'Tomato', Category: 'Vegetable', Price: 3.21, 'Shopping Place': 'Other' },
        { Name: 'Sandwich', Category: 'Food', Price: 2, 'Shopping Place': 'Wal-Mart' },
        { Name: 'Hamburger', Category: 'Food', Price: 2, 'Shopping Place': 'Wal-Mart' },
        { Name: 'Grape', Category: 'Fruit', Price: 4, 'Shopping Place': 'Sun Store' }
      ];
      columnWidth = 100;
      workbookInit(args: { spread: GC.Spread.Sheets.Workbook; }){
        let spread:GC.Spread.Sheets.Workbook = args.spread;
        let sheet = spread.getActiveSheet();
        sheet.getCell(0,0).text("My SpreadJS Angular Project").foreColor("blue");
      }
    }
  6. 使用 Angular CLI 构建和运行项目

    接下来,您可以使用以下命令来构建和运行新项目:

    ng serve
