I am trying to use siunitx package to format tables, but it just doesn't seem to be working. I am using texlive2012 installation under ubuntu 12.04. A minimal "working" example would be:




  {Test2} \\
  0.23 \\


When trying to compile this, it just gives me 3 errors with "undefined control sequence" - here an excerpt from the output:

l.14   {
        Test2} \\
! Undefined control sequence.
<recently read> ...gnore_spaces_execute_branches: 

l.15   0
        .23 \\
! Undefined control sequence.
<recently read> ...gnore_spaces_execute_branches: 

l.16   0

It would be great if someone could help me here ...

Thanks, Juergen

Welcome to TeX.SE! When I run your MWE on a system with MacTeX2011 with the latest versions of all packages installed, I don't get any error messages. When did you perform the most recent run of tlmgr update --self -all on your system? – Mico Aug 18 '12 at 11:08
You code also works with me (TL2012 + siunitx 2012/07/22 v2.5g). I believe a package update might help. :) – Paulo Cereda Aug 18 '12 at 11:11
Indeed, that is an error due to mismatched package versions. You have an updated siunitx but older l3kernel/l3packages. – Joseph Wright Aug 18 '12 at 11:12
Well, that was the solution :-) Thanks a lot! – Juergen Aug 18 '12 at 12:05
