Table Width 100%

Hello, is there a sure fire way to force a table to always be 100% wide? Sometimes when I shrink the browser and then open it back up there is a huge space on the right hand side because the table is not 100%. What can be done about this?

can you send a sample of what you mean? I have been through several forms of displaying tables corrcectly, but need some frame of refference.

ehmm…would need to see an example but to have a table the size of the page you would set the height and width to 100%
