title: How to assign background color to <p-column> depends upon field values in angular4
body: <p>I created one primeNG table. In that I want to assign background color depends upon the field value. If field value is between 50% to 60% I want to assign red color. If field value is between 60% to 70% I want to assign yellow color. If field value is above I want to assign green color. How I do it?
