i am having a problem laying out tables to fit on other tables perfectly ( with or without using frames .
let's say i have a table with a 100 pix width aligned to the middle then i make another one right under it same width ( 100 pix ) yet they don't exactly "stack up" ... if i have a line of color on the side it does fit ! if i alighn everything to the left that it "adds up" so i am guessing my problem has to do with the centering of the table and the contact but what exactly am i doing wrong ??

thanks for any help
