Table Border Help needed

[Dirk Bromberg]

Hi, i've written an "generic table modell" which creates the fo code for a table. Inline is a sample of the table as screenshot. My problem are the borders in cell which don't have a top and bottom border, here the line in the middle. You can see that the border is thicker than the border in the first and last line... The Table has border-collapse="separate" and each Cell has a: border-top="[EMAIL PROTECTED]" border-bottom="[EMAIL PROTECTED]" border-left="[EMAIL PROTECTED]" border-right="[EMAIL PROTECTED]" with: “none” or “1mm solid gray” as value. Is there a better was to create such borders?   What is the mistake? Thanks. Dirk
