Showing image in data table is one of major requirements in projects. In this post, we will see how we can show image in Lightning Web Component Data Table. In last blog Integrate Salesforce Stackexchange using Lightning Web Component and Apex I have created community to show Salesforce StackExchange user list. Let us add profile picture of user in same community.
By default datatable does not support image data type. We have to create custom data type for image in Lightning Web component.
Steps for creating custom data type
- Custom Control Creation
- Extend Lightning Data Table
- Use extended data table in Component
1. Custom Control Creation
Create custom control for showing profile pics. For this we need to create a lightning web component with below code. We are using img control to show profile pic and source for this image will be passed at runtime using @api parameter.
2. Extend Lightning Data Table
We have to extend lightning data table to show image in table row. Create another Lightning Web Component named ‘salesforceCodexDataTable’ . Create imageTableControl.html in same folder to use above created image control to show profile pics. This file is used as custom type while extending data table.
Folder structure for custom components:
3. Use extended data table in Component
After image custom data type is created for data table. Let us use this in component to show profile pics of Salesforce Stack Exchange User on community portal.
Here we have used image type to show profile pic in line no 3. fieldName: ‘profile_image‘ is having profile image url which is passed to image control as source url.

Hello Dhanik,
In imageTableControl.html you have the url attribute set to value, yet it looks like value is never defined in the js. How does this work? I ask because I notice you are hardcoding the alt-text as “Image Not Found” and I would like to know how to pass an alt-text through as well.
Thank you
Hello Charles,
Url values is passed from data table records in showProfile.js. Please check https://salesforcecodex.com/2020/04/extend-lightning-datatable-with-file-upload-element-in-lightning-web-component/ for passing Alt-text through parameter. You can use typeAttributes for this purpose.
Thank You,

Great post Dhanik!
In this case how would you propagate click in imageControl component to showProfile component? It is useful for one of the projects i’m doing right now
Great post Dhanik!
In this case how would you dispatch an onclick event from imageControl to showProfile component?
Thank You Shiran,
You can add events for this. Checkout post https://developer.salesforce.com/docs/component-library/documentation/en/lwc/lwc.events_handling for this.

Hi folks,
Awesome article. Can we use this solution for lighting tree grid.
Yes Hassan, As per documentation lighting-tree-grid is not supporting custom data type so you will not able to do this. You can try your custom tree grid control.

Hi Dhanik,
We are getting following error,
LWC1011: Failed to resolve import “./imageTableControl.html” from “salesforceCodexDataTable.js”. Please add “imageTableControl.html” file to the component folder.
please help us to resolve this issue.
Thanks,
Vishnu
Hello Vishnu,
imageTableControl.html should be in same folder as salesforceCodexDataTable is. If not then add proper path in importing it in SalesforceCodexDataTable js.
Thank You,Dhanik
