Is there a way for "style sheets" to define "Type as" per each column

[yarikoptic]

or may be even add computed columns etc, so I could just open a particular .tsv file and immediately have those types applied (and potentially new columns created or even hidden etc).

Ideally to be flexible enough so we could construct such styling "dynamically" based on our already existing types specification which could be found in custom form in a .json file nearby. The target use case is .tsv files within BIDS specification for neural data as outlined at https://bids-specification.readthedocs.io/en/stable/common-principles.html#tabular-files .

This thread might have information that is useful: #1488

In that thread look for knownCols and afterLoad. Also mentioned in that thread, look for "autotune" and skeept's guessType command.

Also, recently in #2872

Also, look for other discussions about "autotune".
