insertRow ещё актуально использовать?

Почему, если из этого кода

function tableCreate() {
        //body reference 
        var body = document.getElementsByTagName("body")[0];

        // create elements <table> and a <tbody>
        var tbl     = document.createElement("table");
        var tblBody = document.createElement("tbody");

        // cells creation
        for (var j = 0; j <= 2; j++) {
            // table row creation
            var row = document.createElement("tr");

            for (var i = 0; i < 2; i++) {
                // create element <td> and text node 
                //Make text node the contents of <td> element
                // put <td> at end of the table row
             var cell = document.createElement("td");    
                  var cellText = document.createTextNode("cell is row "+j+", column "+i); 

                cell.appendChild(cellText);
                row.appendChild(cell);
            }

            //row added to end of table body
            tblBody.appendChild(row);
        }

        // append the <tbody> inside the <table>
        tbl.appendChild(tblBody);
        // put <table> in the <body>
        body.appendChild(tbl);
        // tbl border attribute to 
        tbl.setAttribute("border", "2");
    }

убрать var tblBody = document.createElement("tbody");

то таблица не будет создана? 

Ведь tbody браузер автоматически вроде создаёт
