delete unwanted space in environments

[Uwe Brauer]

Hi all


It sometimes happens that after using 
    1. LaTeX-fill-environment and

    2.  LaTeX-align-tabular (a command provided by Arash unofficially
       
https://tex.stackexchange.com/questions/557959/emacs-auctex-tabular-vertical-alignment-of-cells

I end up with expression like this in environments:

            &\textcolor{blue}{-           
\int\limits_{\mathbb{T}^{3}}^{}e^{\pmb{\kappa}\Omega t}\left( 
e^{\pmb{\kappa}\Omega t}\partial_t\Phi 

So between - and \int there is a lot of unwanted space. I can delete
this manually by using delete-horizontal-space, but what I am looking
for is a function that runs region wise

I googled with zero success, any ideas?

Regards

Uwe Brauer
