 A lookup table is a collection of key and value pairs. Both key and value are represented using double precision [[wp>Floating_point | floating point numbers]], allowing the definition of integral and fractional keys and value pairs.
-Optionally, a table may include a key and value name.

+It is possible to load the editor content importing the value from a [[wp>Comma-separated_values|CSV file]]. It is also possible to export the content to a [[wp>Comma-separated_values|CSV file]].

+Two rows can be used to interpolate other rows in between. The keys are created incrementing the lower selected key until the greatest selected key is reached. The values are interpolated linearly between the two original selected values.
+The table can also be presented as a graph using different representations.
