This script can be used to transpose LaTeX tables. Simply copy and paste your
current LaTeX tabular field in transpose_latex_tables.py, run the script and
copy and paste the output back to LaTeX.
However, note that this script is not clever and will not work for all LaTeX tables. Things like midrules, multirow, multicolumn, etc. will not work. Only straight forward tables with "&" and "\" will work. Also, this script only takes the main "tabular" part of the table as input.
The script is tested with Python 3.8.
