<template> 
     
    <lightning-card title = "Search Accounts" icon-name = "custom:custom63"> 
 
        <div class = "slds-m-around_medium"> 
 
            <lightning-input type = "search" onchange = {handleKeyChange} class = "slds-m-bottom_small" label = "Search" > 
            </lightning-input> 
 
            <template if:true = {accounts}> 
                 
                <div style="height: 300px;"> 
 
                    <lightning-datatable key-field="Id" 
                                         data={accounts} 
                                         columns={columns} 
                                         hide-checkbox-column="true" 
                                         show-row-number-column="true"
                                         onrowaction={handleRowAction}> 
                    </lightning-datatable> 
 
                </div>                  
     
            </template> 
     
            <template if:true = {error}> 
 
                {error}> 
                 
            </template> 
 
        </div> 
 
    </lightning-card> 
 
</template>



Component JS:

import { LightningElement, track } from 'lwc'; 
import fetchAccounts from '@salesforce/apex/AccountController.fetchAccounts';
import { NavigationMixin } from 'lightning/navigation';

const actions = [
    { label: 'View', name: 'view' },
    { label: 'Edit', name: 'edit' },
];
 
const columns = [   
    { label: 'Name', fieldName: 'Name' }, 
    { label: 'Industry', fieldName: 'Industry' },
    {
        type: 'action',
        typeAttributes: { rowActions: actions },
    }, 
];

export default class LightningDataTableLWC extends NavigationMixin( LightningElement ) {
     
    @track accounts; 
    @track error; 
    @track columns = columns; 
 
    handleKeyChange( event ) { 
         
        const searchKey = event.target.value; 
 
        if ( searchKey ) { 
 
            fetchAccounts( { searchKey } )   
            .then(result => { 
 
                this.accounts = result; 
 
            }) 
            .catch(error => { 
 
                this.error = error; 
 
            }); 
 
        } else 
        this.accounts = undefined; 
 
    }

    handleRowAction( event ) {

        const actionName = event.detail.action.name;
        const row = event.detail.row;
        switch ( actionName ) {
            case 'view':
                this[NavigationMixin.Navigate]({
                    type: 'standard__recordPage',
                    attributes: {
                        recordId: row.Id,
                        actionName: 'view'
                    }
                });
                break;
            case 'edit':
                this[NavigationMixin.Navigate]({
                    type: 'standard__recordPage',
                    attributes: {
                        recordId: row.Id,
                        objectApiName: 'Account',
                        actionName: 'edit'
                    }
                });
                break;
            default:
        }

    }

}



Apex Class:

public with sharing class AccountController { 
 
    @AuraEnabled( cacheable = true ) 
    public static List< Account > fetchAccounts( String searchKey ) { 
     
        String strKey = '%' + searchKey + '%'; 
        return [ SELECT Id, Name, Industry FROM Account WHERE Name LIKE: strKey LIMIT 10 ]; 
         
    } 
     
}
