wordpress tables borders

On my wordpress site I have got tables but I and visitors can't see table borders and background colors.How can I solve this problem?
note:wordpress 2.7 wirh premiumnews theme

 

Here is the solution

<table border="1">
<tr><td bgcolor="#FF0000">Red background</td></tr>
<tr><td bgcolor="#0000FF">Blue background</td></tr>
</table>

Hope this help

 

Background is ok but i can't still see borders.

 

Maybe try it like this:

<table border="2" cellpadding="0" cellspacing="0" bordercolor="#000000">
<tr><td bgcolor="#FF0000">Red background</td></tr>
<tr><td bgcolor="#0000FF">Blue background</td></tr>
</table>

Where bordercolor="#000000" is the color you want the border.

 

I think same you.Try to do it.

 

i think so

 

Thank you all contributors helping me to get solved my problem.

 

one of the key reason why borders cannot be turned on or off in html is due to the border being defined in CSS, solution is to control the border purely in css or remove from css so you can control it in html

 

You are right but i couldn't find the related codes in .css in my wp theme.
