I don't know of any text editors that don't render variable width tabs based on the tabstop position. In programming environments we usually only use tabs at the beginning of the line for indentation, it's a bit more rare to use them for alignment due to inconsistent tabstop settings.

There's also Elastic Tabstops if you want to go all in on using tabs for alignment: https://nick-gravgaard.com/elastic-tabstops/
