Sorting in tables is sometimes lexicographic instead of numeric

[JonOfUs]

Hi,
upon using your cool site, I noticed that sorting in tables seems to not recognize the datatype of the cells correctly. All cells with numeric data where some kind of text is also present, the sorting is done by alphabetical order and not by numerical value:

I never used datatables, so I am not sure how to fix this issue. But some people on the internet™ write that the natural sorting plugin should do exactly that.
I wasn't able to test this because I couldn't get the software to run on my computer. Could you, if you find the time, maybe also write a small build and install summary for this project so that one can better test ideas and maybe support you in maintaining/improving the project?
