The 2D Lookup Table (or Lookup Table 2 D) component computes an output signal by two-dimensional interpolation of a data table, using the input values $u$ and $v$.

The first column of the table contains the values of $u$, the first row of table contains the values of $v$.

If the table has only one element, the output is independent of the input signal, that is, the table value is returned as the output.

The data source parameter selects the source for the data. It can be either file, attachment, or inline.

For all data source options, elements $2$ though m of the first column in the data table correspond to the input $u$, and elements $2$ through n of the first row correspond to the input $v$.

The data table must have at least $2$ rows and at least $2$ columns. For a $2$ by $2$ data table, the output is constant and corresponds to the value in the second row and second column of the data table.
