First, install odslatex. Then, clone this repo and run
pip install .
Just run odslatex_qt once you have installed it. To use this program, open a .ods file you want converted to LaTeX. The spreadsheets it contains will be converted and put into different tabs. Select the table you want, and click on "Clipboard". The contents will be automatically copied to your clipboard. Now you can paste the table in your LaTeX document.
