I have a problem using the cleveref package in combination with the built-in \appendix command. I receive the following error: "Missing number, treated as zero..." as soon as I activate the \appendix command. If no appendix is used, the document compiles well. Please see the minimal ...

I found an answer. This is achieved with a \phantom{} command that takes the width of a given parameter, i.e. in the example above to insert a phantom minus write:


\phantom{-}(E_1 - E_2)/\dx
- (E_3 - E_4)/\dy
- \Jsrc


to obtain the desired result:


(E1 - E2)/dx
- (E3 - E4)/dy
- Jsrc

Dear LaTeX community,

I would like to align the equation terms to the left inside a "{pmatrix*}[l]" environment, but at the same time bypass the leading minus sign of selected terms:

original equation:


(E_1 - E_2)/\dx - (E_3 - E_4)/\dy - \Jscr


normal {pmatrix*}[l] result:


(E1 - E2)/dx ...
