Trying to create a 'one cell' table using dynamic arrays...

Hi Dazzathedrummer 

Not sure this is what you expect (if not provide a picture of the expected result):

With data formatted as table named Table1:

=LET(
  StackCat, LAMBDA(init,type,
      VSTACK(init, type, FILTER(Table1, Table1[Type] = type), "")
  ),
  array,    DROP( DROP( REDUCE(0,UNIQUE(Table1[Type]), StackCat), 1), -1),
  kcols,    SEQUENCE(,COLUMNS(array)),
  IFNA( FILTER(array, IF(kcols = 2, 0, kcols)), "")
)
