Description
A DESCRIPTION OF THE PROBLEM :
Many code editors and components support tab lines — vertical guide lines that visually indicate tab stops or indentation levels. These lines are extremely helpful for maintaining consistent indentation and improving code readability.

Currently, JavaFX's CodeArea does not support this feature. So I suggest to add this feature.
