I've gone to advanced table properties; I can make all columns wider or narrower, but I can't make some narrower than others--
Try editing the Cell Properties of the first cell in each column. I was able to vary the width of columns by doing this; although I didn't see the change until I saved and then edited a second time.
You can also click and drag the line, same as in Excel! I found this our by playing around with it. Just as Rick stated, you won't see it until you save.
