I have a visualforce page that has a records data displayed as a PDF.  The background for the columns on the left need to be blue.  However using a CSS file it is only ht e text background that turns blue.  The rest of the cell has a white background.  Looking on the internet it might be that the <DIV> tags screw this up.  Anyway I need to have the entire cell background in blue, any help appreciated.

<apex:page controller="CVRRead" showHeader="false" sidebar="false" renderas="pdf">
