 ## Example
 
 The example below shows how to calculate the exact count of unique values. The function takes an array of numbers (values) as an input and calculates the exact count of unique values using the **reduce** method. The **distinct_count** sub-property has a handler with a function that calculates the distinct count value from an array of numbers.

 ### Switching to the tree mode
 
 The widget allows presenting data in a hierarchical format with expandable rows. To switch to the tree mode, apply the `tree` parameter of the [`tableShape`](/api/config/tableshape-property) property by setting its value to **true** (default is **false**).

 The widget provides the following default methods for data aggregation:
 
-- Sum (for numeric values only) - sums all the values of the selected data property and displays the sum
-- Min (for numeric and date values)- finds and displays the minimum value of the selected data property  
-- Max (for numeric and date values) - finds and displays the maximum value of the selected data property  
-- Count (for numeric, text, and date values) - looks for all occurrences of the selected data property and displays their number; this is the default operation assigned to each newly added field
-- Average (for numeric values only) - calculates the average value of an array
+- sum (for numeric values only) - sums all the values of the selected data property and displays the sum
+- min (for numeric and date values)- finds and displays the minimum value of the selected data property  
+- max (for numeric and date values) - finds and displays the maximum value of the selected data property  
+- count (for numeric, text, and date values) - looks for all occurrences of the selected data property and displays their number; this is the default operation assigned to each newly added field
+- average (for numeric values only) - calculates the average value of an array
+- counta (for numeric, text, and date values) - counts the number of cells in a range that are not empty
+- median (for numeric values only) - calculates the median of an expression (middle value in a sorted data set), which separates the higher half in a distribution from the lower half
+- product (for numeric values only) - calculates the product of all numbers in a given range
+- stdev (for numeric values only) - calculates the standard deviation of a sample, which measures the amount of variation or dispersion of a set of values; quantifies the amount of variation or dispersion of a set of values
+- stdevp (for numeric values only) - similar to stdev, but this calculates the standard deviation of a population
+- var (for numeric values only) - calculates the variance of a sample, which measures how much each number in the set differs from the mean (average) and then squares that value
+- varp (for numeric values only) - similar to var, but this calculates the variance of a population
