Joomla table cut off

I'm running a PHP script in Jumi in a Joomla article that outputs html code for a table, given some fancy pants through开发者_StackOverflow a CSS file. The problem is that the table is cut off mid-point for some users, I see the whole thing. I'm new to web development, what could be the reason?

Ask questions about what OS, Web Browser, and Plugins are installed. Recreate their environment on your end and try to reproduce the problem. If you can reproduce it, then debug and fix. If you cant reproduce the problem, then you need to deal more deeply with your clients / users.
