SFDC Falcon

Component Overview

This implementation creates a custom Lightning Datatable component that:

Displays images in table cells
Uses custom column types
Maintains all standard datatable functionality
Works in all Salesforce environments

Key Features

Custom Column Types: Extends LightningDatatable with new column type
Image Display: Shows images from URLs in table cells
Reusable Component: Can be used across your org
Lightning Design: Matches Salesforce UI standards

Implementation Steps

Follow these steps to implement this solution:

1. Create the Parent Component

This component configures and uses the custom datatable.

HTML (customDataTable.html)

<template>
    <c-custom-data-table-type-controller
        key-field="id"
        data={data} 
        columns={columns} 
        hide-checkbox-column
    ></c-custom-data-table-type-controller>
</template>

JavaScript (customDataTable.js)

import { LightningElement, track } from 'lwc';

// Table column definitions
const columns = [   
    { label: 'Name', fieldName: 'name' },
    { label: 'Model', fieldName: 'type' },
    { 
        label: 'Image',
        fieldName: 'imageUrl',
        type: 'imageColumenForDataTable', // custom column type for image
        typeAttributes: {
            imgUrl: { fieldName: 'imageUrl' }
        }
    },
];

export default class customDataTable extends LightningElement {
    accountData;
    header = [];
    columns = columns;

    // Table data
    @track data = [
        { id: 1, name: 'Hyundai', type: 'Creta', buttonname: 'CS1', imageUrl:'https://imgd.aeplcdn.com/370x208/n/cw/ec/106815/creta-exterior-right-front-three-quarter-5.jpeg?isig=0&q=80'},
        { id: 2, name: 'Toyota', type: 'Fortuner', buttonname: 'EC2', imageUrl:'https://imgd.aeplcdn.com/664x374/n/cw/ec/44709/fortuner-exterior-right-front-three-quarter-21.jpeg?isig=0&q=80'},
    ];
}

2. Create the Custom Data Table Controller

This extends LightningDatatable to support the custom image column type.

JavaScript (customDataTableTypeController.js)

import { LightningElement } from 'lwc';
import LightningDatatable from 'lightning/datatable';
import imageColumenForDataTable from './imageColomManage.html';

export default class customDataTableTypeController extends LightningDatatable {
    static customTypes = {
        imageColumenForDataTable: {
            template: imageColumenForDataTable,
            typeAttributes: ['imgUrl']
        }
    };
}

3. Create the Custom Column Template

This defines how the image column should be rendered.

HTML (imageColomManage.html)

<template>
    <img src={value} alt="Table image" style="max-height: 50px;"/>
</template>

How to Use This Component

Create all three LWC components in your Salesforce org
Deploy the components to the appropriate pages
Configure the parent component with your data:
- Update the columns array to match your field structure
- Provide your data in the data property
- Ensure image URLs are accessible (consider CORS restrictions)
Add any additional custom column types as needed

Best Practices

Image Optimization: Use properly sized images to improve performance
Error Handling: Add error handling for broken image links
Accessibility: Include proper alt text for images
CORS: Ensure your image URLs are accessible from Salesforce
Security: Validate image URLs to prevent XSS vulnerabilities

Enhancement Ideas

Potential Improvements

Image Preview: Add lightbox functionality for full-size viewing
Lazy Loading: Implement lazy loading for better performance
Placeholder Images: Show placeholders while images load
Dynamic Sizing: Allow configurable image dimensions
Upload Functionality: Add in-line image upload capability
