I have the following HTML table

HTML

<table width="100%" id="tbl1" cellpadding="4">
	<tr>
		 <td bgcolor="#F2F2F2" class="FieldNames">
			Table Data
		</td>     
	</tr>
	<tr style="display: inline-block;">
		 <td bgcolor="#F2F2F2" class="FieldNames">
			Table Data
		</td>     
	</tr>
	<tr id="tr1">
		<td bgcolor="#F2F2F2" class="FieldNames">
			Table Data
		</td>                                                        
	</tr>
</table>

if I am accessing this table rows in JavaScript it only shows 2.

JavaScript

var tbl1= document.getElementById('tbl1');
alert(tbl1.rows.length);//return only 2

If i remove the 'style="display: inline-block;"' from middle row, it is working fine and returning 3.

Is there any DOM processing related changes in IE-11?

Just put following HTML code in a HTML file. Run and click on the button. Issue will be visible

HTML

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <title>Manish Test</title>
   <script type="text/javascript" lang="javascript">
        function showcount()
        {
            var tbl1= document.getElementById('tbl1');
            alert(tbl1.rows.length);//return only 2
            return false;
        }
    </script>
</head>
<body>     
    <table width="100%" id="tbl1" cellpadding="4">
	<tr>
		 <td bgcolor="#F2F2F2" class="FieldNames">
			Table Data
		</td>     
	</tr>
	<tr style="display: inline-block;">
		 <td bgcolor="#F2F2F2" class="FieldNames">
			Table Data
		</td>     
	</tr>
	<tr id="tr1">
		<td bgcolor="#F2F2F2" class="FieldNames">
			Table Data
		</td>                                                        
	</tr>
</table>
    <input type="button" id="btnTest" value="Test" onClick="showcount();" />
</body>
</html>

My IE-11 exact version is 11.0.9600.16428

What do you want to achieve with such pretty strange styling? Especially when you have only one "td" per row, which would pretty defeats the purpose of table...

I have just imitated the actual problem statement. In actual table there are 4 tds per tr.

Could you then make your sample more realistic and point out what do you want to achieve with this inline-block?

I just run it in IE11 and got 3!!!
Maybe you missed some code?

Can you recheck with complete HTML which I have added later in question?

A TR displays a table-row by default, and apparently changing that to inline-block ensures that IE11 no longer considers it to be a row. No idea why it does that, but that's not important. You need to deal with the fact that it does and work around it (welcome to the wonderful world of web development). I suggest using jQuery or some other library. With jQuery you can simply do this:
