        var tr,td;
         //获得行列值
        var tr_value = document.getElementById("tr_value").value;
        var td_value = document.getElementById("td_value").value;
      for(var i=0;i<tr_value;i++){
        //循环插入元素
        tr = table.insertRow(table.rows.length);
        if(i%2 === 0){
          tr.style.backgroundColor = "#D5E3D0";
