Filling 3-D Look Up Table in Matlab

While trying to use a 3-d look-up table, it is showing an error : " the number of dimensions in the table data parameter must match the number of dimensions indicated."

my breakpoint sets are

a - 0,1

And table data is

a b c data

0 1 1 2

Please help me in filling the 3-d look-up table.
