Angular Material 7 – 表格

<mat-table>是Angular指令，用于创建带有材质设计和样式的表格。

本章节将展示使用Angular Material显示表格所需的配置。

下面是修改后的模块描述文件 app.module.ts 的内容。

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppComponent } from './app.component';
import {BrowserAnimationsModule} from '@angular/platform-browser/animations';
import {MatTableModule} from '@angular/material'
import {FormsModule, ReactiveFormsModule} from '@angular/forms';
@NgModule({
   declarations: [
      AppComponent
   ],
   imports: [
      BrowserModule,
      BrowserAnimationsModule,
      MatTableModule,
      FormsModule,
      ReactiveFormsModule
   ],
   providers: [],
   bootstrap: [AppComponent]
})
export class AppModule { }

下面是修改后的HTML host文件 app.component.html 的内容。

<table mat-table [dataSource] = "dataSource" class = "mat-elevation-z8"> 
   <ng-container matColumnDef = "name">
      <th mat-header-cell *matHeaderCellDef> 甜点 (100克) </th>
      <td mat-cell *matCellDef = "let element"> {{element.name}} </td>
   </ng-container>
   <ng-container matColumnDef = "calories">
      <th mat-header-cell *matHeaderCellDef>卡路里</th>
      <td mat-cell *matCellDef = "let element"> {{element.calories}} </td>
   </ng-container>
   <ng-container matColumnDef = "fat">
      <th mat-header-cell *matHeaderCellDef>脂肪 (克)</th>
      <td mat-cell *matCellDef = "let element"> {{element.fat}} </td>
   </ng-container>
   <ng-container matColumnDef = "carbs">
      <th mat-header-cell *matHeaderCellDef>碳水化合物 (克)</th>
      <td mat-cell *matCellDef = "let element"> {{element.carbs}} </td>
   </ng-container>
   <ng-container matColumnDef = "protein">
      <th mat-header-cell *matHeaderCellDef>蛋白质 (克)</th>
     <td mat-cell *matCellDef = "let element"> {{element.protein}} </td>
   </ng-container> 
   <tr mat-header-row *matHeaderRowDef = "displayedColumns"></tr>
   <tr mat-row *matRowDef = "let row; columns: displayedColumns;"></tr>
</table>

下面是修改后的CSS文件 app.component.css 的内容。

table {
   width: 100%;
}

下面是修改后的ts文件 app.component.ts 的内容。

import {Component, Injectable} from '@angular/core';

   protein: number;
}
@Component({
   selector: 'app-root',
   templateUrl: 'app.component.html',
   styleUrls: ['app.component.css']
})
export class AppComponent { 
   dataSource: Food[] = [
      {name: '酸奶', calories: 159, fat: 6, carbs: 24, protein: 4},
      {name: '三明治', calories: 237, fat: 9, carbs: 37, protein: 4},
