This is nice, but I have one critique: Having the sorting indicators right justified and the text for the column header left justified without any column borders had my clicking on the sorting indicators for the wrong column for a few seconds and wondering why the sorting was wonky. You can click anywhere on the header column to sort, which once you realize that makes it easy to use as intended, but a visual indication of separate columns in the header (a right/left border, or horizontal striping) would make it just a tad more obvious.
Nice table, it provides a good overview of what is available. I would suggest also to add the protocol (S3, Swift,...) used and coverage by libs/languages.
