Hi sanjay.joshi,
I can not reproduce this issue.
Here are my steps to test:
2.Click the New Document button to clean the code
3.Click HTML link to switch to THML view and enter the following code
<table width="590" border="0" align="center" cellpadding="0" cellspacing="0" style="border: black 1px solid;
background-color: #FFFFFF" xmlns:msxsl="urn:schemas-microsoft-com:xslt">
<tr>
<td>
<table cellspacing="0" cellpadding="0" width="590">
<tr width="100%">
<td>
Test</td>
</tr>
</table>
</td>
</tr>
</table>
4.Click Normal link to switch to Normal view
5.Click HTML link to switch to HTML view again
Here is the new code:
<table style="border-right: black 1px solid; border-top: black 1px solid; border-left: black 1px solid; border-bottom: black 1px solid; background-color: #ffffff" cellspacing="0" cellpadding="0" width="590" align="center" border="0" xmlns:msxsl="urn:schemas-microsoft-com:xslt">
<tbody>
<tr>
<td>
<table cellspacing="0" cellpadding="0" width="590">
<tbody>
<tr width="100%">
<td>Test</td>
</tr>
</tbody>
</table>
</td>
</tr>
</tbody>
</table>
If you still have this issu, please provide you steps to reproduce this issue, I will do more test.
