[SalesForce] How to navigate to records using Datatable in Lightning Web Components

I am new to Lightning Web Components. I have a wrapper class that returns Accounts, Leads, and Contacts. I display those using lightning data table in my LWC. I want to navigate to a particular record by clicking on it. I used onRowAction attribute of datatable and NavigationMixin for navigation but it gives me page doesn't exist error. Please guide. Also, can I use name in the form of hyperlink for navigation?

Javascript

import { LightningElement,api,track, wire } from 'lwc';
import getWrapperLis from '@salesforce/apex/WrapperClass.getWrapperList';
import { NavigationMixin } from 'lightning/navigation'; ///Navigation

const actions = [
    { label: 'View', name: 'show_details' },
];

const columns = [
    {
        type: 'action',
        typeAttributes: {
            rowActions: actions,
        }
    },
    { label: 'Label', fieldName: 'name', type:'text' },
    { label: 'Email', fieldName: 'email', type: 'email' , sortable:'true' },
    { label: 'Phone', fieldName: 'phone', type: 'phone', sortable:'true'  },
    { label: 'MDM ID', fieldName: 'mdm', type: 'text' , editable:'true' },
];

export default class WrapperClassTestNavigation extends NavigationMixin(LightningElement) {
    @api recordId;
    @track columns = columns;

    @wire(getWrapperLis,{lead:'$recordId'}) wrappers;

    navigateToRecordViewPage(event) {
        const row = event.detail.row;

        // View a custom object record.
        this[NavigationMixin.Navigate]({
            type: 'standard__recordPage',
            attributes: {
                recordId: row.Id,
                //objectApiName: 'Lead', // objectApiName is optional
                actionName: 'view'
            }
        });
    }
