You can find the CuteEditorconstants.js under CuteSoft_clients/CuteEditor.

>>We want to set the default value of cell padding = '0' , cell border = '0' 

Table cell doesn't have those properties.  Check this link: http://msdn.microsoft.com/library/default.asp?url=/workshop/author/dhtml/reference/objects/td.asp

>>cell alignment to 'left' and cell vertical allignment to 'top'. 
 

When creating a new table, align and vAlign are not set by default.

 

<table cellSpacing="0" cellPadding="3" border="1" style="width: 320px; border-collapse: collapse">
       <tbody>
           <tr>
              <td></td>
              <td></td>
              <td></td>
           </tr>
           <tr>
              <td></td>
              <td></td>
              <td></td>
           </tr>
       </tbody>
   </table> 

You need to set align and vAlign using the table cell property dialog.

  <table cellSpacing="0" cellPadding="3" border="1" style="width: 320px; border-collapse: collapse">
       <tbody>
           <tr>
              <td vAlign="top" align="left"></td>
              <td></td>
           </tr>
           <tr>
              <td></td>
              <td></td>
           </tr>
           <tr>
              <td></td>
              <td></td>
           </tr>
       </tbody>
   </table>
   <br/>
</div>
