Sort
This transformation sorts the table by one or more columns in ascending or descending order. Order of the columns matters.
Since values of a column can be of mixed types, the sorting order depends on the value type. For ascending sorting, the order is as follows:
- Errors
- Empty cells
- Boolean values
- Text
- Numbers
In descending order, the sorting order is exactly the opposite.
