I have two questions regarding creating the legend in ArcMap 10.2.2:

 1. In the attribute table of my shapefile I change the number of decimals from 6 to 2; I can see the changes in the attribute table but in the legend and symbology still the full values are shown. 
So the question is how can I have the number of decimals that I need in symbology and  legend.
 2. I created a legend to show two fields by using " categories" option of symbology.
As you see the values are not in a column (Image).
I want to know How can I have two  nice individual columns for my text and values.
