how to delete unwanted space with a function or macro

Hi

I just used plain align on the table below.



\begin{tabular}{|l|l|}

It has a lot of unwanted space as in \(e^{a t}\) how can I delete this
space in a convient way, whitespace-cleanup for example ignores this
space. Any ideas?

Maybe using regex replace using \( \)\{2,\}  which means 2 or more
consecutive spaces; replace that with 2 spaces.
