Hi, ccrayton, and welcome to the forum!
Actually, the Mac version is several years ahead the Windows version. You can read about the most relevant details on this thread.
Tables, OTOH, have several restrictions on both platforms, since they are provided by the underlying text engine (which is different on each platform) and not via a specific development from L&L. You can read some history and future ideas here.
However, you can do mostly the same operations on both environments, it’s just that sometimes the command are different. Try the right-click menu for specific options and commands.
Hope this helps!
