I have prepared a sample code based on my understanding of your requirement ,It may help you
<!DOCTYPE html>
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
<script>
$(document).ready(function(){
$("#trid1").hide();
$("#trid2").hide();
var noofField=2;
$("#text").focusout(function(){
if($.isNumeric( this.value ) )
{
for(i=1;i<=this.value;i++)
{
$("#trid"+i).show();
}
if(this.value<noofField)
{
var j=noofField-this.value;
for(k=0;k<=j;k++)
{
var l=parseInt(this.value)+j;
$("#trid"+l).hide();
}
}
}
});
});
</script>
</head>
<body>
<p>If you click on the "Hide" button, I will disappear.</p>
<table>
<tr>
<td>
<input type="text" value="" id="text">
</tr>
<tr id="trid1">
<td>
<input type="text" value="1">
</td>
</tr>
<tr id="trid2">
<td>
<input type="text" value="2">
</td>
</tr>
</body>
</html>
in the above code based on value entered in the first input field ( id=text) the other two field are shown
