Add not 1 but 2 to 3 rows at a time?

Question

I have worked hard at my project and with my question can someone help me in which no one did. Maybe it is because it was too long and the length of the code was throwing people off. That wasn't the whole code. Anyways I have managed to add 1 row to the from table. I makes me happy to see it work. But my leader is not satisfied yet. He wants to see the program adding several rows at a time.
function addRow()
        var tbody = document.getElementById("table2").getElementsByTagName("tbody")[0];
        var row = document.createElement("TR");
                var cell1 = document.createElement("TD");
                              cell1.innerHTML = "Ïä×ӳߴç";
                var cell2 = document.createElement("TD");
                              var inp1 =  document.createElement("INPUT");
                              var inp2 =  document.createElement("INPUT");
                              var inp3 =  document.createElement("INPUT");
                              var inp4 =  document.createElement("INPUT");
                              cell2.innerHTML = "³¤£º";
                        inp1.setAttribute("type","text");
                        inp1.setAttribute("value","");
                              inp1.setAttribute("size" ,"8");
                        cell2.appendChild(inp1);
                              cell2.appendChild(document.createTextNode("Ó¢´ç ¿í£º"));
                              inp2.setAttribute("type","text");
                        inp2.setAttribute("value","");
                              inp2.setAttribute("size" ,"8");
                        cell2.appendChild(inp2);
                              cell2.appendChild(document.createTextNode("Ó¢´ç ¸ß£º"));
                              inp3.setAttribute("type","text");
                        inp3.setAttribute("value","");
                              inp3.setAttribute("size" ,"8");
                        cell2.appendChild(inp3);
                              cell2.appendChild(document.createTextNode("Ó¢´ç"))
                              inp4.setAttribute("type","text");
                        inp4.setAttribute("value","");
                              inp4.setAttribute("size" ,"8");
                        cell2.appendChild(inp4);
                var cell3 = document.createElement("TD");
                        cell3.innerHTML = "1Ó¢´ç = 2.5399ÀåÃ×"
          //Result
          row.appendChild(cell1);
        row.appendChild(cell2);
        row.appendChild(cell3);
        tbody.appendChild(row);This code adds 1 row, so the question is how i add another row within the same time as a click of 1 button. What i need to add to allow this to happen?
Please kindly give a response, as any tips and words of wisdom is very much appreciated

Answer 1

I am surprised by
var row = document.createElement("TR");
I would have expected
var row = tbody.createElement("TR");
