Actually l, r and c are already supported. You can enter them into the
dialog when creating a math array (the "horizontal" entry box, which
takes lrc, and | to create a vertical line), or you can edit using
Edit->Math or Edit->Rows&Columns.
It doesn't seem @{} or >{} are supported though, and it would be
challenging to do -- unless you do it in the same way as Tabular, by
allowing raw LaTeX user input. The code to look at is MathGridInset.
Note BTW that the Tabular user interface for doing this has been
criticized and should probably be reworked as well.
