table cell padding and spacing does not work

Hey there

I’m having lots of trouble with table cell padding and spacing to my wordpress pages.

I have tried the following plug ins:
tinymce advanced and FCK editor

I have used both of these to add the tables and set the cell padding and spacing to how I want it to look in the page editor, and when I ‘preview changes’ the tables NEVER have any cell padding or spacing – no matter what I do, it never seems to add these settings to the table. In the page editor I CAN see the cell padding and spacing, but not in the ‘published page’.

I have also tried this code and set the cell padding to 20 and still nothing changes, all the cells are butted up next to each other with no padding or spacing.
<table style=”text-align: center; height: 152px;” border=”1″ cellspacing=”20″ cellpadding=”20″ width=”390″>

<tbody>

<tr style=”background-color: #e9e9e9; font-weight:bolder;”><td>Month</td>
<td>Mobile Networks</td>
<td>Month</td>
<td>Mobile Networks</td>
</tr>

<tr>
<td>Argentina</td>
<td>Movistar</td>
<td>Argentina</td>
<td>Movistar</td>
</tr>

<tr>
<td>Argentina</td>
<td>Movistar</td>
<td>Argentina</td>
<td>Movistar</td>
</tr>

</tbody>

Can someone pleeeeaaase help me! I’m starting to go crazy working this out!

Thanks
