As Iggyvolz said, if you want to round-off the corners of rectangular objects such as tables or bordered divs or whatever, add to either your CSS page or, if using in-line styling, to a style attribute, border-radius:5px; replacing the 5 with whatever number you want, although I find 5 to be a nice starting point.
