fixing fieldset, div whatever Options

[asmith]

hey guys

i have a table with rows (don't important) which is placed in a fieldset . my page content div is about 700 . so this fieldset has stretch to 700 and there's table in it . the table can grow bigger by width or height. the height is not important to me , but when the width of the table grows more than 700 , it streches the whole content area and makes the page look kinda ulgy ,
i wanted to know how can i fix that "700" , so when the table grows in width more than 700 , it just add a scroll bar at down of that area (not down of the browser) , so the page remain in 700 , but user could scroll throw left and right ?

thanks in advance

ps. (please most-browsers support version ! ` ) <-- ( i think this sentence always mean please IE support!)
