• exception traceback:

• reason:

>>> type(None)(None)

TypeError: NoneType takes no arguments

• solution:

str(cell) if _isnumber(cell) else _type(cell, numparse)(cell)
to
str(cell or '') if _isnumber(cell) or cell is None else _type(cell, numparse)(cell)

Seems very related: I get "list index out of range" when there are no elements to tabulate and maxcolwidths is set (e.g. tabulate([],maxcolwidths=[2])):

File ....venv/lib/python3.12/site-packages/tabulate/__init__.py:2054, in tabulate(tabular_data, headers, tablefmt, floatfmt, intfmt, numalign, stralign, missingval, showindex, disable_numparse, colalign, maxcolwidths, rowalign, maxheadercolwidths)
   2051 list_of_lists, separating_lines = _remove_separating_lines(list_of_lists)
   2053 if maxcolwidths is not None:
-> 2054     num_cols = len(list_of_lists[0])
   2055     if isinstance(maxcolwidths, int):  # Expand scalar for all columns
   2056         maxcolwidths = _expand_iterable(maxcolwidths, num_cols, maxcolwidths)

Writing here since basically the same code area/workflow
