View source for Visualizzare i segni di tabulazione ed a capo con vim

You can use 
 :set list
(which defaults to "nolist"), which shows tabs as ^I and puts a "$" at the end of lines. 

You can also define highlighting regions with "syn match" to define a single tab. 

You can then link this to whatever highlighting you like perhaps using the following:

 :syn match TAB_CHAR "\t"
 :hi link TAB_CHAR Error
