You could redefine the tabular environment used by LyX. However, you
cannot use the GUI for setting tabular properties. Another difficulty is
the fact that LyX uses \tabularnewline instead of \\ to end a line and,
seemingly, the tabularray package does not understand it. So you have
also to redefine \tabularnewline and remember to add \\ in ERT at the
end of each table line.
Arguments such as "width=10cm,colspec={X[c]},rows={ht=2cm},hlines,vlines"
can be passed through the "LaTeX argument" in the "Tabular Settings"
paying attention to avoid any space character.
See the attached example containing two examples in both ERT and a
somewhat LyXfied form as explained above. This last form is marginally
better than the ERT one.
