This is only a example, just to tell you that your problem can be solved in this way. It is very easy to modify it by yourself, isn't it?

师兄，你的两个我都试了，我在table的tr中多加一个<td><input></td>，代码还是在第一个input得到回车后，就换行了。显然还需要改进呀，谢谢

<table>
<tr><td><input onkeypress="addNewLine(this)"></td></tr></table>
<script>
function addNewLine(it) {
if (event.keyCode == 13) {
var thisLine = it;
while (thisLine.tagName != "TR") {
thisLine = thisLine.parentNode;
}
var newLine = thisLine.cloneNode(true);
var inputbox = newLine.firstChild.firstChild
inputbox.value = "";
thisLine.parentNode.appendChild(newLine);
inputbox.focus();
//----------forbid event for other line---
it.onkeypress = null
//----------------------------------------
}
}
</script>
