• For the second column, to count, we define an expression like

  Code Block
  How many times:([count])

  It defines a label to be used (How many times) and the expression to calculate ([count]). You can use Supported math operators, formulas and functions and you can have references to filed values in expressions via [entry.field_name] notations

• [count] and [total] are special context variables available in TableViewMerger. [count] shows the records count for a grouped by key, while [total] holds a total number of records in the dataset

So, for the data like this:

you will get this calculated with TableViewMerger like this:
