Introduction

In today's web development landscape, creating interactive and dynamic data tables is a common requirement. Angular Bootstrap, a powerful framework that combines the functionality of Angular and the aesthetics of Bootstrap, provides an excellent solution for building such tables. In this article, we will guide you through the process of creating a Data Table using Angular Bootstrap. We can also easily use Angular Contrast with easy syntax to create the same appealing UI Data table.

what is Datatables

Datatables are simply tables with options that can be used to configure and process the data to be displayed.

What is Contrast?

Contrast Design Bootstrap, popularly known as Contrast, was developed by Devwares. It is an amazing UI kit with a vast number of components that helps make the development process a breeze. Contrast incorporated bootstrap into its core, making it all the more functional, responsive, and elegant. This goes without saying. By installing Contrast in your project, bootstrap is also tagged along. It’s like getting two amazing products for the price of one. What a bargain!

Contrast has offered one of the components the data table component, which is functional and easy to use. The data table component mixes tables with advanced options like searching, sorting, and pagination.

What is Angular Bootstrap

Angular Bootstrap is a powerful and popular web framework used by developers to create dynamic user interfaces. It is used to create a wide variety of web applications, such as web-based data tables. Data tables are a great way to display and manage large amounts of data. They make it easy to search, filter, and sort data quickly and efficiently.

Creating a data table using Angular Bootstrap is relatively easy, as long as you have some basic HTML and JavaScript knowledge. This tutorial will walk you through the steps of creating a data table with Angular Bootstrap.

PREREQUISITES

This Datatable will be built using Angular, Bootstrap, and Contrast (ng-cdbangular-pro). You don’t need to have any prior knowledge of CBAugular, but the following are necessary:

A basic understanding of Angular
A basic understanding of Bootstrap
NPM installed

Let’s get started, shall we?

STEP 1

Get the Pro version of Contrast from here .

STEP 2

Add the ng-cdbangular-pro tgz file to your projects root folder and run this command in your terminal:

npm install --save ng-cdbangular

STEP 3

Add Contrast Pro’s assets and bootstrap-css-only to angular.json

"assets": [
{
"glob": "**/*",
"input": "node_modules/ng-cdbangular-pro/assets",
"output": "/assets/"
}
],
"styles": [
"node_modules/bootstrap-css-only/css/bootstrap.min.css"
]

STEP 4

Import table module in app.module.ts
import { TableModule } from 'ng-cdbangular-pro';
@NgModule({
imports: [ TableModule ]
})

NB, for our example, we will be needing some other components so our final app.module.ts file will look like this;

import { TableModule, CardModule } from 'ng-cdbangular-pro';
@NgModule({
imports: [ TableModule, CardModule ]
})

Note: instead of importing one component at a time, the contrast has a module called CDBProModule which contains the imports of all the custom components contrast has to offer.

import { CDBProModule } from 'ng-cdbangular-pro';
@NgModule({
imports: [CDBProModule]
})

Easy right? Now let’s go on. Contrast’s data table component has quite a lot of boilerplate code, so let’s go through it. In the .component.ts file, paste the following code snippets:

import { Component, OnInit, ViewChild } from '@angular/core';
import { CdbTableDirective } from 'ng-cdbangular-pro';

export class ExampleComponent implements OnInit {
  @ViewChild(CdbTableDirective, { static: true }) CdbTable: CdbTableDirective;

  pages = [];
  activePage = 0;
  previousData;
  entries = [5, 10, 15];
  searchText: string = '';
  elements: any = [

  ngOnInit(): void {
    this.CdbTable.\_activePage.subscribe(data => {
      this.activePage = data;
    });

    this.CdbTable.setEntries(this.entries[0]);
    this.CdbTable.setDataSource(this.elements);
    this.CdbTable.setPages();
    this.previousData = this.CdbTable.getDataSource();
    this.pages = this.CdbTable.pages;
  }

  searchItems() {
    const prev = this.CdbTable.getDataSource();

    if (!this.searchText) {
      this.elements = this.CdbTable.getDataSource();
      this.CdbTable.setDataSource(this.previousData);
      this.CdbTable.setPages();
      this.pages = this.CdbTable.pages;
    }

    if (this.searchText) {
      this.CdbTable.setDataSource(this.previousData);
      this.elements = this.CdbTable.filterData(this.searchText);
      this.CdbTable.setDataSource(this.elements);
      this.CdbTable.setPages();
      this.pages = this.CdbTable.pages;

  changeEntries(e) {
    this.CdbTable.setEntries(e.target.value);
    this.CdbTable.setPages();
    this.pages = this.CdbTable.pages;
    this.CdbTable.\_activePage.next(0);
  }

  sort() {
    this.pages = this.CdbTable.pages;
  }
}

The elements property should contain your custom data and the headElements should contain your data’s thead values. By passing enabled to the enableSort option, you give the table head (thead) the ability to sort the data by ascending value and descending value. To disable this, just pass “disabled” to the “enableSort” option. The entries property should contain the customizable number of data values to be shown per page. P.S, everything apart from elements, headElements and entries should be left alone.

<CDBCardBody>

This example made use of another Contrast component called CDBCard for purely visual purposes. The result looks like this: Whew! We’ve come to the end of this article. I hope it was as fun and informative.

Contrast’s Datatable component ships with a lot of customizable features. For more information, please check out the docs .
