How it looks

Module Setup (app.module.ts)

import { SpreadTableModule } from "spread-table";

@NgModule({
  imports: [
    // Other module imports
    ...// spread-table modules
    SpreadTableModule,
  ],
})
export class AppModule {}

Usage (app.component.ts)

import { HttpClient } from "@angular/common/http";
import { Component } from "@angular/core";
import { Column } from "spread-table";

@Component({
  selector: "app-root",
  templateUrl: "./app.component.html",
  styleUrls: ["./app.component.scss"],
})
export class AppComponent {
  title = "spread-table-test";
  columns: Column[] = [new Column({ displayName: "Id", name: "id", editable: false, resizable: false }), new Column({ displayName: "Album Id", name: "albumId", minWidth: 120 }), new Column({ displayName: "Title", name: "title", minWidth: 400, validators: [RequiredValidator.required(), RequiredValidator.requiredString()] }), new Column({ displayName: "Url", name: "url", minWidth: 300 }), new Column({ displayName: "Thumbnail Url", name: "thumbnailUrl", minWidth: 300 })];

  data: any;

  gridInstance: ISpreadTable = new SpreadTable();

  @ViewChild("spreadTable") set grid(gridInstance: SpreadTable) {
    this.gridInstance = gridInstance;
  }

  constructor(private httpClient: HttpClient) {
    this.getData();
  }

  private async getData() {
    const products: any = this.httpClient.get("https://jsonplaceholder.typicode.com/photos");
  }
}

Usage (app.component.html)

<div class="p-3 w-100" style="height: 700px;">
  @if(this.data){
  <spread-table #spreadTable [columns]="columns" [minColumnWidth]="100" [rowHeight]="36" [indexWidth]="60" [rawData]="data" [undoRedoStackSize]="20" [extraContextMenuItems]="extraContextMenuItems" [extraColumnMenuItems]="extraColumnMenuItems" (cellValueChange)="onCellValueChange($event)" (contextMenuEvent)="onContextMenuEvent($event)" (columnMenuEvent)="onColumnMenuEvent($event)"> </spread-table>
  }
</div>

Validators

In order for the validators to work correctly they have to be custom. Even the required validator. This way you can set a custom message for the error. See the example bellow:

(required-validator.ts)

import { AbstractControl, Validators } from "@angular/forms";

export class RequiredValidator extends Validators {
  public static required() {
    return (control: AbstractControl): { [key: string]: any } | null => (control.value ? null : { required: "This field is required" });
  }
}

(app.component.ts)

columns: Column[] = [
    new Column({
      displayName: "Id",
      name: "id",
      width: "40px",
      editable: false,
    }),
    new Column({
      displayName: "Album Id",
      name: "albumId",
      width: "70px",
      validators: [RequiredValidator.required()]
      }),
    ...
  ];

Idea behind

The idea was to implement a web spreadsheet with minimal functionality. The beauty of this plugin is that you can build on this and implement your custom scenarios rather than use some generic implementation of different features.

Note: This plugin is till work in progress
