I think the application could use TAB characters to get to the next
cell, then simplistic reordering would also work.

But in general, yes: this is one of the examples why sophisticated
text-editing applications cannot leave this to the terminal.  (Another
example is handling mouse clicks, if the terminal supports that.)
