Dear All,

I'm trying to get a nested alignment in math mode:

+----------------------------------------------------------------+
| ..... & ................                                       |
|       +--------------------------------------------------+     |
|       | ..... & .................                        |     |
|       |         .............................            |     |
|       +--------------------------------------------------+     |
+----------------------------------------------------------------+

Using

    \startformula
      \startalign
        \NC ..... \NC ................ \NR
	\NC       \NC \startalign
		      \NC ..... \NC ................. \NR
		      \NC       \NC .............................
		      \stopalign
      \stopalign
    \stopformula

does not produce the desired result.

How can I achieve this alignment?

Thanks in advance and best regards,

Marko
