How To Create A Data table in Angular 10 Using Bootstrap And Contrast

AD-BANNER

What is a Data table?

Data tables are simply tables that have 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 that has 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 also tags along. It’s like getting two amazing products for the price of one. What a bargain! One of the components Contrast has to offer is 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. This article is going to show you, step by step, how to create a bootstrap angular data table using contrast.

PREREQUISITES

This Data table will be built using Angular, Bootstrap, and Contrast (ng-cdbangular-pro). You don’t need to have any prior knowledge of ng-cdbangular-pro 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 ./ng-cdbangular-pro-1.0.0.tgz

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"
]
Enter fullscreen mode Exit fullscreen mode

STEP 4 

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

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]
})
Enter fullscreen mode Exit fullscreen mode

Note: instead of importing one component at a time, 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]
})
Enter fullscreen mode Exit fullscreen mode

Easy right? Now let’s go on. Contrast’s data table component has quite a lot of boiler plate 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 = [

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.

This example made use of another Contrast component called CDBCard for purely visual purposes. The end result looks like this: Whew! We’ve come to the end of this article. I hope it was as fun and informative as it was for me for you. Please click this link and navigate to the Data table page to see the live demo. Contrast’s Data table component ships with a lot of customizable features. For more information, please check out the docs.
