Close, but it's exactly the other way round: it's the *first*
array dimension that can be left open, i.e.:

   unsigned char table011[][2] = {{ 0, 0},

is the right way.

And, as a related issue, no initialized variable definition like this
should usually be put into a header file. You'ld get "multiple
definition" errors from the linker, if this header file is linked into
more than one .c file.  Instead, have 'extern unsigned char
table[][2];' in the header, and move the initialized definition into
the .c file (or a 'private header' which is not made visible to users
of this code module).
