Edit Mode
You can create display fields with the DisplayFields tab. Display fields are areas of the cell such as the decimal separator or decimal section of the number. You can set colors, fonts, patterns, and other properties for the display field. The value in the cell is displayed in the order that you list the display field options. For example, NumberIntegerPartDisplayFieldInfo is listed before NumberDecimalSeparatorDisplayFieldInfo in the following image. This means that the integer part of the number is displayed before the decimal separator. You can add, insert, or clone the display fields. You can also delete, clear, or move the fields up or down in the list.
