If a data table contains data that allows interpolating, you can interpolate the table linearly. To interpolate data within a data table, see the following instructions.
The Interpolate dialog box appears.
The value that you add must be greater than the smallest value and smaller than the greatest value in the Range Values list.
Tedds performs the interpolation and updates the table to include the new value.
If you make selections within a table, the Data Tables window automatically transfers the existing selection to the interpolated value.
