We have found 8 software records in our database eligible for .ods to .pdf file format conversion.
You can export OpenDocument spreadsheets (.ods) to PDF format using a dedicated export, or with a virtual PDF printer in most, especially open-source, spreadsheet editors.
Just keep in mind that after you perform ods to pdf conversion (print to pdf really) you won't be able to edit the tables in PDF format, as the format is suited for printing and sharing - not editing. But some programs can import it back and recover the tables should you need it.
