HTML table problem

I have an html problem with a table. Look at the file attached: the table has a width of 600 and is devided in two colums: one of 235 pixels and the other of 365 pixels. When i look at it in dreamweaver, it looks just fine, but when i test the html file in my browser, it messes it up. The first column si shrinked. I want someone to fix this and also tell me what the problem was. This should be an easy job and should not take more than a few minutes, so i will not pay you. The only reward for this job will be a 10 review. If you don't agree with this, please do not bid! This is urgent!
