Hello,
I don't know if this is the right Forum for this servlet PB.
Anyway .... Here goes !!!!
I am in the process of writing a servlet that generates an HTML page. My servlet draws a Financial Results HTML page. The page contains an image and a table with caption, heading and body. I have to have part of the table heading with a white font on a blue background and the rest of the table content with a black font on an alternating white and peach background for each row.
I tried different approaches such as using the FONT COLOR, BGCOLOR and different combinations but it does not give me the desired effect.
Any feedback is appreciated.
Thanks in advance,
Paolo
