Work around of using 1D-LUT instead of 2D-LUT

Dear All,

I originally have a look up table of size UInt8[256][256].

However, there is a restriction that just 1D look up table of size
UInt8[256] can be use. The no. of UInt8[256] tables to be used is not
limited.

Are there any simple method for me to constructing many 1D look up
tables of UInt8[256] so that the same result can be obtained as if the
2D-LUT UInt8[256][256] is used?

Note that the 1D-LUT can just have max. no. of element of 256. Ans
just +,-,*,/ operations can be used.
Thank you,
Jason
