You need to write a class using OOP to work with a table. I wrote a constructor, but for some reason it does not work, it says that this.elem.insertCell() is not a function! Although insertRows() works fine.
Please tell me where I screwed up
JavaScript

let rows = 1, cells = 1;
class Table{
    constructor(){
        this.elem = document.createElement('table');
        this.elem.style.border='5px';

        document.body.appendChild(this.elem);

        this.elem.insertRow().innerHTML = "- - - - -"; // вставить строку 1 (работает)
        this.elem.insertRow().innerHTML = "| | | | |";  // вставить строку 2 (работает)
        
        this.elem.insertCell().innerHTML = "X X X X X"; // выдаёт ошибку

    }
    
}

let elem = new Table();

insertCell is a row(TableRow) method and you are trying to apply it to a table.
