I would get rid of all inline styling and put it in an external stylesheet.

It will make it a lot easier to work on.

Also, do not use meaningless class names like style2 and style4. Name them for what they *do*.

Welcome to WebmasterWorld rockbk.. btw g1smd. a code review was NOT the question?

rockbk, you can't attach a pic it's not what we do here, there's no Personal URI's at all, (imagine you were happening on this thread in 6 months time would you be happy if the answer you found relied on a dead/fixed link?) if you could post a bit of sample code (don't care whether it's valid code or not despite the previous answers) - we should be able to help

please read the sticky posts, and then be sure and tell us are you talking table code or table "display" code?
