The only shortcuts that allow for non-adjacent cell selection on tables is `COMMAND+LEFT_CLICK`. This requires the use of a mouse on top of keyboard inputs.

Apple Pages has no support at all for these table navigation functions other than `COMMAND+LEFT_CLICK`. Excel has a selection mode that can be toggled on/off using SHIFT+F8. I also tested in macOS's `System Preferences > Keyboard > Text` and `CMD+CLICK` is the only supported way to select non-adjacent cells as well.

The two paths to fixing this issue was either adding the shortcuts and functionality to Aqua L&F tables or to make the test exclude macOS. The benefit of adding the shortcuts to Aqua allows for users to navigate without the need for a mouse or touchpad. The Oracle doc for tables [here](https://docs.oracle.com/javase/tutorial/uiswing/components/table.html) shows that `CTRL+ARROW` is a supported keyboard action as an alternative for `CTRL+CLICK`, and has no mention of excluding macOS or Aqua L&F. 

So, I thought it is appropriate to add the shortcuts to Aqua, but I can make changes if needed.
