Step 1:- Create Apex Controller : lwcAppExampleApex.cls

SFDX:Create Apex Class >> New >> lwcAppExampleApex.cls

lwcAppExampleApex.cls [Apex Class]

  public with sharing class lwcAppExampleApex {

  
    // Create a lightning-datatable and display modal on rowaction
    @AuraEnabled(cacheable=true)
    public static List<Contact> getDataFromContact(){
      List<Contact> conList = [Select Id, FirstName, LastName, Email, Phone From Contact limit 10];
      try{
         return conList;
      }
      catch(Exception e){
         throw new AuraHandledException(e.getMessage());
      }
    }

}

public with sharing class lwcAppExampleApex {

// Create a lightning-datatable and display modal on rowaction

@AuraEnabled(cacheable=true)

public static List<Contact> getDataFromContact(){

List<Contact> conList = [Select Id, FirstName, LastName, Email, Phone From Contact limit 10];

try{

return conList;

}

catch(Exception e){

throw new AuraHandledException(e.getMessage());

}

Step 2:- Create Lightning Web Component : lwcDataTableRowAction.html

lwcDataTableRowAction.html [Lightning Web Component HTML]

  <template>
    <lightning-card title="Create a lightning-datatable and display modal popup on rowaction in LWC" icon-name="custom:custom14">

</div>

<lightning-button variant="brand" label="Close" title="Close" onclick={closeModalAction}></lightning-button>

</footer>

</div>

</section>

</template>

</lightning-card>

</template>

Step 3:- Create Lightning Web Component : lwcDataTableRowAction.js

SFDX:Lightning Web Component >> New >> lwcDataTableRowAction.js

lwcDataTableRowAction.js [LWC JavaScript File]

  import { LightningElement, track, wire } from 'lwc';
import getDataFromContact from '@salesforce/apex/lwcAppExampleApex.getDataFromContact';
const columns=[
    {
        label: 'View',
        type: 'button-icon',
        initialWidth: 75,
        typeAttributes: {
            iconName: 'action:preview',
            title: 'Preview',
            variant: 'border-filled',
            alternativeText: 'View'
        }
      },
      {
        label: 'First Name',
        fieldName: 'FirstName'
    },
    {
        label: 'Last Name',
        fieldName: 'LastName'
    },
    {
        label: 'Email',
        fieldName: 'Email'
    },
    {
        label: 'Phone',
        fieldName: 'Phone'
    }
];

export default class LwcDataTableRowAction extends LightningElement {
  @track columns = columns;
  @track contactRow={};
  @track rowOffset = 0;  
  @track modalContainer = false;
   @wire(getDataFromContact) wireContact;
 
   handleRowAction(event){
      const dataRow = event.detail.row;
      window.console.log('dataRow@@ ' + dataRow);
      this.contactRow=dataRow;
      window.console.log('contactRow## ' + dataRow);
      this.modalContainer=true;
   }

   closeModalAction(){
    this.modalContainer=false;
   }

}

import { LightningElement, track, wire } from 'lwc';

import getDataFromContact from '@salesforce/apex/lwcAppExampleApex.getDataFromContact';

const columns=[

{

label: 'View',

type: 'button-icon',

initialWidth: 75,

typeAttributes: {

iconName: 'action:preview',

title: 'Preview',

variant: 'border-filled',

alternativeText: 'View'

}

{

label: 'First Name',

fieldName: 'FirstName'

{

label: 'Last Name',

fieldName: 'LastName'

{

label: 'Email',

fieldName: 'Email'

{

label: 'Phone',

fieldName: 'Phone'

}

];

export default class LwcDataTableRowAction extends LightningElement {

@track columns = columns;

@track contactRow={};

@track rowOffset = 0;

@track modalContainer = false;

@wire(getDataFromContact) wireContact;

handleRowAction(event){

const dataRow = event.detail.row;

window.console.log('dataRow@@ ' + dataRow);

this.contactRow=dataRow;

window.console.log('contactRow## ' + dataRow);

this.modalContainer=true;

}

closeModalAction(){

this.modalContainer=false;

}

Step 4:- Create Lightning Web Component : lwcDataTableRowAction.js-meta.xml

SFDX:Lightning Web Component >> New >> lwcDataTableRowAction.js-meta.xml

lwcDataTableRowAction.js-meta.xml [LWC Meta Data XML]

  <?xml version="1.0" encoding="UTF-8"?>
<LightningComponentBundle xmlns="http://soap.sforce.com/2006/04/metadata">
    <apiVersion>45.0</apiVersion>
    <isExposed>true</isExposed>
    <targets>
        <target>lightning__AppPage</target>
        <target>lightning__RecordPage</target>
        <target>lightning__HomePage</target>
      </targets>
</LightningComponentBundle>

<?xml version="1.0" encoding="UTF-8"?>

<target>lightning__AppPage</target>

<target>lightning__RecordPage</target>

<target>lightning__HomePage</target>

</targets>

</LightningComponentBundle>

Step 5:- Create Lightning Application : lwcApp.app

From Developer Console >> File >> New >> Lightning Application

lwcApp.app [Component Application File]

  <aura:application extends="force:slds">
  <c:lwcDataTableRowAction/>
</aura:application>

<aura:application extends="force:slds">

<c:lwcDataTableRowAction/>

</aura:application>
