I can make the column widths wider BUT can't make them get any narrower on my Customer Balance Detail report.  I tried using different browsers so that's not the problem.  Even though the print preview shows all the columns, the printed product cuts off all the dates!  

Look at all the questions and comments about this issue, which has been complained about for over two years.  Can't QBO hire someone to fix this extremely basic, critical and annoying problem?  Boy, do I miss QB Desktop!! The Online development team squeezed all of the Desktop's flexibility and intuitive thinking right out of the Online version.
