I needed to get this going so I added a 4th pricing column. but my question is still there. If I only had 3 columns in the pricing table, how could I center it in one of the widgets?
It’s difficult to center divs that “float” left or right. So you could probably just increase the width in your css (search for pricing plans) so they stretch and fill up the entire space in the same way 4 columns do. So just play around with the width until you get the size you need.
