Wordpress Themes - WP Forum at BFA - Editing the table style and in the posts

I've noticed when i changed to this theme, my tables (a big picture in the middle and below a 3x2 table with pictures in them) have changed into the borders being black and the inside being white and making it a little bigger as well. It being bigger, it expands my page and it doesn't fit into the layout.

Now, in the theme options there is a table page, is that what i edit to change all my tables in the posts? I'm not sure what kind of code i need to put in there, i just want a black border around the images and it being only a thin line (smallest if possible).

This is what i have always used in the post itself:

Code:

<center>

<table bgcolor="#000000" border="1">

<tr>

<td bgcolor="#000000"><a href="" rel="lightbox[dbz]" title=""><img src="" height="290" width="600"></a></td>

</tr>

</table>

</center>

<table bgcolor="#000000" border="1">

<tr>

<td bgcolor="#000000"><a href="" rel="lightbox[]" title=""><img src="" height="160" width="270"></a></td>

<td bgcolor="#000000"><a href="" rel="lightbox[]" title=""><img src="" height="160" width="270"></a></td>

<td bgcolor="#000000"><a href="" rel="lightbox[]" title=""><img src="" height="160" width="270"></a></td>

</tr>

<tr>

<td bgcolor="#000000"><a href="" rel="lightbox[]" title=""><img src="" height="160" width="270"></a></td>

<td bgcolor="#000000"><a href="" rel="lightbox[]" title=""><img src="" height="160" width="270"></a></td>

<td bgcolor="#000000"><a href="" rel="lightbox[]" title=""><img src="" height="160" width="270"></a></td>

</tr>

</table>

Now, what code should i put in the table style and what should i put in the post itself?
Also, will i need to edit all my previous posts with the tables so that they will fit?

I'm sorry, i've always been new to this (not to mention i took the html from above from a page a long time ago heh) Also, the

Code:

rel="lightbox[]"

is a wordpress image addon.
