Sometimes, some characters of text are missing, and only half of your numbers are right. Have a close look at this preview of your data. If you then click on "Preview & Export Extracted Data", you will see how Tabula interpreted your selection: To do so, you can click and drag a selection.

There are many tools out there that try to solve this problem. If we then try to copy and paste the numbers from there into a spreadsheet, the columns and/or rows won't translate: Often, our data doesn't come in a neat Excel sheet or csv, but is buried as a table in a PDF, like in this report by the United Nations: This article explains three tools to extract data tables out of PDFs: The open-source tool Tabula and the commercial tools, smallpdf and cometdocs.
