The closest solution I can suggest is:
Click on Eclipse IDE > Window > Preferences > General > Editors > Text Editors
Then click on the link "whitespace characters" to specify what should be shown.
Then enable tick box "Leading and Enclosed" for Tab only and leave the rest unchecked.
This is not perfect solution, but it might be useful.
