I don't think this is easily possible.

If you examine invoice.tex you'll see that items' price & (price x  
quantity) are displayed using the  <?lsmb sellprice ?> and <?lsmb  
linetotal ?> variables.

I'm not VAT-registered myself, so I'm not sure off the top of my head  
whether these include tax or not, but I don't believe there's an  
alternative (tax inclusive or exclusive, whichever) version.

Unless I'm mistaken in this belief, displaying the columns as you  
desire would require using LaTeX's maths functions to recalculate or  
reverse-calculate the figures with or without tax - this is quite  
clumsy, as you'd effectively be doing so _outside_ of Ledger-SMB.

If I'm correct in my understanding of the the  <?lsmb sellprice ?>  
and <?lsmb linetotal ?> variables you'd be best off revising your  
requirements if at all possible and submitting a feature request for  
tax inclusive / exclusive alternatives.
