Left click to select measurement and drag to move to the right panel one at a time, or when you mouse over on a measurement, click on the green plus button to move to the right panel. When Sample (Cell) is select, the calculation will be performed on all the features in the input matrix for each sample (or cell). When Feature is selected, the calculation will be performed across all the samples (cells) in the input matrix  for each feature.

In addition, when Feature is selected, there is an extra Group by option (Figure 3)

From the drop-down list, choose a categorical attribute to calculate the descriptive statistics on all the subgroups for each feature

The output of the task is a matrix, it can be visualized in data viewer
