上面的那些javascript里面的各个设置td的innerHTML属性的代码里,按照你自己的要求来添加或者修改其他表单都可以的。

<table id="table1"><tr><td></td><td></td><td></td></tr></table>

<script>
function AddNew(){
var newRow;
var newCell;
newRow = table1.insertRow();
newCell=newRow.insertCell();
newCell.width="164";
newCell=newRow.insertCell();
newCell.innerHTML="<select><option value='0'>0</option></select>"
newCell.width="164";
newCell=newRow.insertCell();
newCell.innerHTML="<select><option value='1'>1</option></select>"
newCell.width="164";

移除掉某些tr（tr是动态添加的）尝试了很多方法，都不见效，后来发现个不错的方法，于是与大家分享下

1.js动态生成table,对table的创建，添行，删行操作
