• The last row does not have the same height as the previous rows. It's off by a couple of pixels. I'm not setting the height of the grid, it's parent div or anything like that, so I don't know why this is happening.
  
  
• I want three of the columns to disappear when the browser resolution gets below a certain size (when the device is a phone used in portrait mode). When the resolution changes to trigger the style change, the data columns are hidden, but the headers are still there.
