Can you reword this - the description makes it sound as though it returns a list in row major order (which is what you'd naively expect) but it actually returns it in column-major order.

It's not a file anymore, it's just a table

Good but I think can you do something to make the error messages nice again - it's a pet hate of mine when something raises an error about a file but then doesn't tell you which file it is!
Perhaps just wrap the outer parse function like:
def lookup_table_from_file(filename: str,
lookup_for_columns: Callable[[Sequence], Callable[[float], float]]) -> Callable[[float], float]:
try:
columns = parse_lookup_table(filename)
except Exception as e:
# log message here
raise
return lookup_for_columns(*columns)
However this may heading down the road of too much boilerplate for some, so I leave it up to you if you want to do this or not.
…ble files (#981) * First idea for beam center, may move compute to plans * Actually make it a plan * Fix the tests * Tidy up docstring * Reword comments

Split the linear_interpolation_lut into two different functions so that it can be used for lookup tables that have more than 2 columns in them (eg. DetDistConverter)
Needed for Mx#708
