valign and centering a table - code seems wrong, please look

Hi guys....

Code for table:
*****************************
table#table1 {
position:absolute;
bottom:0px;
text-align:center;
left:50%;
right:50%;

}
*****************************

Code for the footer is:
**************************
.footer {font-size:9px;color:#333333;line-height:16px;}
a.footer,a.footer:visited,a.footer:active,a.footer:hover {font-size:9px;color:#333333;text-decoration:none;}
*************************

My goal is to put this table at the bottom of every html page and centered. The table contains a footer that has its own styles like color, font size.

Everything centers find but as soon as I add the "position:absolute;
bottom:0px;" to the table css code the whole table losses centering. Everything gets outta wack.

Please help.

Thanks
