The comb object describes a comb field, where each letter of the field is divided by a black vertical line that spans the distance between the top and bottom edges of the field. The comb object is available for only dynamic or interactive PDF generation forms. Static PDF forms, and all other output formats, ignore this object.
Only single- line comb fields can be created, and to display field data as a comb, you must set the value of the hand property for the border object of the field to right. The maxChars property on the textEdit object determines the number of combs to create.
Note:
If a textEdit object is a multiline field or a rich-text field, the presence of a comb child object will not produce a comb field at runtime.
