上面是jquery写的一段九九乘法表代码程序了，下面

 var table = "<table>"
    for(var i = 1;i <= 9;i++){
        table += "<tr>";
        for(var j = 1;j <= 9;j++){
            var data = (j <= i ? "" + i + " * " + j + " = " + i*j : "");
            table += "<td>" + data + "</td>";
        }
        table += "</tr>";
    }
    table += "</table>";
    $("body").append(table);

下面是一段简单的写法
