Hi Jackster. Welcome to Scrivener.
I don’t know, and will surely be corrected if wrong, but my guess is that sorting tables is at least as complicated an operation as sorting and editing lists, and the latter is a known problem, not easily fixed, and that using and editing around them is officially likened to handling “unstable dynamite”. This is apparently true of both the Mac and Qt/Windows versions.
There is a Sort option, on the Edit menu, that can be applied to tables, but the main thing it does is break them and strew their contents.
I am happy using Scrivener for what it does, but make it a practice to avoid doing in it anything that requires editing special formatting and layouts, including even simple lists and tables (though the latter I’ve barely touched.) More productive, less heartache that way.
